Hi,

This version of the draft addresses IESG evaluation comments from Benjamin Kaduk, Éric Vyncke, Erik Kline, Magnus Westerlund, Martin Duke, and Robert Wilton, and review comments from Michael Scharf for the Transport Area Review Team, Paul Kyzivat for the General Area Review Team, and the IANA.

The primary technical change is in Section 7, where the relation to RFC 6679 is clarified, and the SDP signalling is updated to allow more graceful fallback to that format. This changes the normative requirements, so needs review by the WG.

The security considerations are also expanded, and there are several minor clarifications are made throughout.

I’m happy to present the changes at IETF 109 if the chairs wish, or we can review on the list.

Colin
