Describing QUIC's Protocol Data Units with Augmented Packet Header
Diagrams
draft-mcquistin-quic-augmented-diagrams-02
Abstract
This document describes the core transport protocol data units used
in the QUIC protocol using a machine-readable augmented packet header
diagram format. It is intended as an example of the packet header
diagram language, and not as a contribution to the development of the
QUIC protocol.
