Document: draft-ietf-mediactrl-call-flows-13.txt (Informational) Reviewer: Brian Carpenter Review Date: 2013-08-26 IETF LC End Date: 2013-09-13 IESG Telechat date: Summary: Ready -------- Comment: -------- This is a massive (175pp) and highly specialised document, for which a generalist review is pretty much useless. I have not checked the example flows, XML extracts, etc. IMHO, we have to trust the authors and the WG in a case like this. The document is clear and where I have sampled the text in the examples it is up to standard. Editorial: ---------- There are a few abbreviations (AS, MS, CFW) that could usefully be included in the Terminology section. Also, AS is widely used in the IETF to mean Autonomous System. Some readers might be confused at first, so this should be stated very clearly. "Mealy automaton" (section 4.1) needs a reference. Or it might be sufficient just to say "finite state automaton."
