The IESG has approved the following document: - 'RTP Stream Pause and Resume' (draft-ietf-avtext-rtp-stream-pause-10.txt) as Proposed Standard This document is the product of the Audio/Video Transport Extensions Working Group. The IESG contact persons are Barry Leiba, Ben Campbell and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-avtext-rtp-stream-pause/ Technical Summary This document provides a mechanism to use existing RTCP Feedback Codec Control Messages (RFC 5104), as well as a group of new messages, to pause and resume RTP media streams. The document defines two separate mechanism for pausing and resuming RTP streams. One mechanism codifies existing practice of how to use RFC 5104 messages to pause and resume streams, but is only applicable to a subset of possible RTP topologies. The other is a new mechanism and is generally applicable. Guidance is provided as to when one or the other mechanism should be used. Working Group Summary The two protocol mechanisms were the result of two separate proposals as to how to solve the requirement; once the proposals were merged into a single document, there were no objections to WG consensus. Document Quality There are existing deployed implementations of the RFC 5104-based mechanisms to pause and resume RTP streams. Paul Kyzivat performed an SDP directorate review. The review expressed concerns about the complexity of configuration. The WG had already considered the suggested alternatives and selected the documented method. The authors added additional text discussing the interoperability considerations of the various supported configurations. Personnel The Document Shepherd is Jonathan Lennox; the Responsible Area Director is Ben Campbell.
