-
This version contains a number of editorial fixes and minor clarifications. It clarifies the rules around uniqueness of PDU and field names, and more clearly states when field lengths can be inferred.

-
This version expands the requirements and further discusses what is an appropriate degree of expressiveness for a protocol description language. It clarifies a number of corner cases in the grammar and specifies how definitions are to be cross-referenced between documents. A list of known open issues is added.

-
This document describes a machine-readable format for specifying the syntax of protocol data units within a protocol specification. This version tries to make the motivation clearer, is revised to describe the format by reference to real examples; and adds support for "PDUs with Non-Contiguous Fields” (e.g., the STUN Message Type Field).

-
This document describes a machine-readable format for fully specifying the process by which a protocol can be parsed. This format combines a consistent ASCII packet diagram format with the use of structured text, maintaining human readability while enabling support for machine parsing. This document is itself an example of how this format can be used.
IETF protocol specifications have long relied on packet header diagrams to illustrate the format of packet headers and other protocol data. This memo describes a consistent, machine readable, syntax for such diagrams.
