The IESG has received a request from the Audio/Video Transport Core Maintenance WG (avtcore) to consider the following document: - 'Explicit Congestion Notification (ECN) for RTP over UDP' <draft-ietf-avtcore-ecn-for-rtp-06.txt> as a Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-03-22. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This memo specifies how Explicit Congestion Notification (ECN) can be used with the Real-time Transport Protocol (RTP) running over UDP, using RTP Control Protocol (RTCP) as a feedback mechanism. It defines a new RTCP Extended Report (XR) block for periodic ECN feedback, a new RTCP transport feedback message for timely reporting of congestion events, and a Session Traversal Utilities for NAT (STUN) extension used in the optional initialization method using Interactive Connectivity Establishment (ICE). Signalling and procedures for negotiation of capabilities and initialization methods are also defined. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-avtcore-ecn-for-rtp/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-avtcore-ecn-for-rtp/ballot/ No IPR declarations have been submitted directly on this I-D.
