The IESG has received a request from the Audio/Video Transport Core Maintenance WG (avtcore) to consider the following document: - 'RTCP Extension for Third-party Loss Report' <draft-ietf-avtcore-feedback-supression-rtp-15.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 2012-03-26. 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 In a large RTP session using the RTCP feedback mechanism defined in RFC 4585, a feedback target may experience transient overload if some event causes a large number of receivers to send feedback at once. This overload is usually avoided by ensuring that feedback reports are forwarded to all receivers, allowing them to avoid sending duplicate feedback reports. However, there are cases where it is not recommended to forward feedback reports, and this may allow feedback implosion. This memo discusses these cases and defines a new RTCP third-party loss report that can be used to inform receivers that the feedback target is aware of some loss event, allowing them to suppress feedback. Associated SDP signalling is also defined. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-avtcore-feedback-supression-rtp/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-avtcore-feedback-supression-rtp/ballot/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
