Stephen McQuistin, Vivian Band, Dejice Jacob, and Colin Perkins,
Describing Protocol Data Units with Augmented Packet Header Diagrams
(.txt|.pdf),
Internet Engineering Task Force,
October 2021,
Work in progress
(draft-mcquistin-augmented-ascii-diagrams-09.txt).
-
Our draft describing a variant of the traditional packet header diagram
that is both human readable and well-enough structured to be parsed
automatically has been updated.
This version adds a section on describing PDUs with Constraints on
Field Sizes, updates the ABNF to match, and updates the examples and
references.

Colin Perkins,
Sending RTP Control Protocol (RTCP) Feedback for Congestion Control in Interactive Multimedia Conferences
(.txt|.pdf),
Internet Engineering Task Force,
October 2021,
Work in progress
(draft-ietf-rmcat-rtp-cc-feedback-07.txt).
-
This version corrects the
RTCP reporting interval calculations to include the overhead of the
SRTCP authentication tag, and updates the explanation to more clearly
describe the calculation. The discussion of group video conferencing
has been removed since there are too many parameters and options to
consider to readily give a representative summary of the overheads.
The section on screen sharing has been removed as offering little
benefit.
