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.

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.

||||||

The TCP offset element was expanded to a maximum of 255 from 16 to
|
|
||||||
allow for the increased size of the header in XML.
|
|

|
|
||||||
|
|

4.2. Example Datagram
|
|
||||||
|
|
||||||
The following is an example UDPoXML datagram with an empty payload:
|
|
||||||
|
|

</payload>
|
|
||||||
</udp>
|
|
||||||
|
|
||||||
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.
|
|
||||||
|

||||||

|
|
||||||
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.

|
||||||

8. Security Considerations
|
|
||||||
|
|
||||||
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.
