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

   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.
