-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
-
-

-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.
-

-\f
-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.

-5. 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]
-\f
-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. DTDs
-
- The Transport DTDs (7.2. and 7.3.) build on the definitions in the
- Network DTD (7.1.)
-
- The DTDs are referenced by their PubidLiteral and SystemLiteral (from
- [XML]) although it is understood that most IPoXML implementations
- will not need to pull down the DTD, as it will normally be embedded
- in the implementation, and presents something of a catch-22 if you
- need to load part of your network protocol over the network.

-
- XML, as a subset of SGML, has the same security considerations as
- specified in SGML Media Types [RFC1874]. Security considerations
- that apply to IP, TCP and UDP also likely apply to BLOAT as it does
- not attempt to correct for issues not related to message format.
