The IESG has received a request from the Audio/Video Transport Extensions WG (avtext) to consider the following document: - 'Duplicating RTP Streams' <draft-ietf-avtext-rtp-duplication-04.txt> as 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 2014-02-04. 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 Packet loss is undesirable for real-time multimedia sessions, but can occur due to congestion, or other unplanned network outages. This is especially true for IP multicast networks, where packet loss patterns can vary greatly between receivers. One technique that can be used to recover from packet loss without incurring unbounded delay for all the receivers is to duplicate the packets and send them in separate redundant streams. This document explains how Real-time Transport Protocol (RTP) streams can be duplicated without breaking RTP or RTP Control Protocol (RTCP) rules. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-avtext-rtp-duplication/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-avtext-rtp-duplication/ballot/ The following IPR Declarations may be related to this I-D: http://datatracker.ietf.org/ipr/1656/
