It does + not specify an Internet standard of any kind. Distribution of this + memo is unlimited. + +Copyright Notice + + Copyright (C) The Internet Society (2002). All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.

All Rights Reserved. + +Abstract + + This document defines a reformulation of IP and two transport layer + protocols (TCP and UDP) as XML applications. + +1. Introduction + +1.1. Overview + + This document describes the Binary Lexical Octet Ad-hoc Transport + (BLOAT): a reformulation of a widely-deployed network-layer protocol + (IP [RFC791]), and two associated transport layer protocols (TCP + [RFC793] and UDP [RFC768]) as XML [XML] applications. It also + describes methods for transporting BLOAT over Ethernet and IEEE 802 + networks as well as encapsulating BLOAT in IP for gatewaying BLOAT + across the public Internet. + +1.2. Motivation + + The wild popularity of XML as a basis for application-level protocols + such as the Blocks Extensible Exchange Protocol [RFC3080], the Simple + Object Access Protocol [SOAP], and Jabber [JABBER] prompted + investigation into the possibility of extending the use of XML in the + protocol stack. Using XML at both the transport and network layer in + addition to the application layer would provide for an amazing amount + of power and flexibility while removing dependencies on proprietary + and hard-to-understand binary protocols. This protocol unification + would also allow applications to use a single XML parser for all + aspects of their operation, eliminating developer time spent figuring + out the intricacies of each new protocol, and moving the hard work of + + + + +Kennedy Informational [Page 1] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + parsing to the XML toolset. The use of XML also mitigates concerns + over "network vs. host" byte ordering which is at the root of many + network application bugs. + +1.3. Relation to Existing Protocols + + The reformulations specified in this RFC follow as closely as + possible the spirit of the RFCs on which they are based, and so MAY + contain elements or attributes that would not be needed in a pure + reworking (e.g. length attributes, which are implicit in XML.) + + The layering of network and transport protocols are maintained in + this RFC despite the optimizations that could be made if the line + were somewhat blurred (i.e. merging TCP and IP into a single, larger + element in the DTD) in order to foster future use of this protocol as + a basis for reformulating other protocols (such as ICMP.) + + Other than the encoding, the behavioral aspects of each of the + existing protocols remain unchanged. Routing, address spaces, TCP + congestion control, etc. behave as specified in the extant standards. + Adapting to new standards and experimental algorithm heuristics for + improving performance will become much easier once the move to BLOAT + has been completed. + +1.4. Requirement Levels + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in BCP 14, RFC 2119 + [RFC2119]. + +2. IPoXML + + This protocol MUST be implemented to be compliant with this RFC. + IPoXML is the root protocol REQUIRED for effective use of TCPoXML + (section 3.) and higher-level application protocols. + + The DTD for this document type can be found in section 7.1. + + The routing of IPoXML can be easily implemented on hosts with an XML + parser, as the regular structure lends itself handily to parsing and + validation of the document/datagram and then processing the + destination address, TTL, and checksum before sending it on to its + next-hop. + + The reformulation of IPv4 was chosen over IPv6 [RFC2460] due to the + wider deployment of IPv4 and the fact that implementing IPv6 as XML + would have exceeded the 1500 byte Ethernet MTU. + + + +Kennedy Informational [Page 2] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + + All BLOAT implementations MUST use - and specify - the UTF-8 encoding + of RFC 2279 [RFC2279]. All BLOAT document/datagrams MUST be well- + formed and include the XMLDecl. + +2.1. IP Description + + A number of items have changed (for the better) from the original IP + specification. Bit-masks, where present have been converted into + human-readable values. IP addresses are listed in their dotted- + decimal notation [RFC1123]. Length and checksum values are present + as decimal integers. + + To calculate the length and checksum fields of the IP element, a + canonicalized form of the element MUST be used. The canonical form + SHALL have no whitespace (including newline characters) between + elements and only one space character between attributes. There + SHALL NOT be a space following the last attribute in an element. + + An iterative method SHOULD be used to calculate checksums, as the + length field will vary based on the size of the checksum. + + The payload element bears special attention. Due to the character + set restrictions of XML, the payload of IP datagrams (which MAY + contain arbitrary data) MUST be encoded for transport. This RFC + REQUIRES the contents of the payload to be encoded in the base-64 + encoding of RFC 2045 [RFC2045], but removes the requirement that the + encoded output MUST be wrapped on 76-character lines. + + + + + + + + + + + + + + + + + + + + + + + + +Kennedy Informational [Page 3] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +2.2.

Network Transport + + This document provides for the transmission of BLOAT datagrams over + two common families of physical layer transport. Future RFCs will + address additional transports as routing vendors catch up to the + specification, and we begin to see BLOAT routed across the Internet + backbone. + +5.1. Ethernet + + BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the + exception that the type field of the Ethernet frame MUST contain the + value 0xBEEF. The first 5 octets of the Ethernet frame payload will + be 0x3c 3f 78 6d 6c ("<?xml".) + +5.2. IEEE 802 + + BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except + that the protocol type code for IPoXML is 0xBEEF. + + + + + +Kennedy Informational [Page 6] + +RFC 3252 Binary Lexical Octet Ad-hoc Transport 1 April 2002 + + +6. Gatewaying over IP + + In order to facilitate the gradual introduction of BLOAT into the + public Internet, BLOAT MAY be encapsulated in IP as in [RFC2003] to + gateway between networks that run BLOAT natively on their LANs. + +7.
