Describing Protocol Data Units with Augmented Packet Header Diagrams
Stephen McQuistin, Colin S. Perkins, Vivian Band · 2000
This document describes a machine-readable format for specifying the syntax of protocol data units within a protocol specification. This format is comprised of a consistently formatted packet header diagram, followed by structured explanatory text. It is designed to maintain human readability while enabling support for automated parser generation from the specification document. This document is itself an example of how the format can be used.
