Sfront currently ships with multi-unicast support, and the implementation is a hybrid of both approaches. A sender does sent the same RTP packet to each receiver, and in this way everything but the lowest layers of the stack believes a true multicast session is underway. Sfront needs to do this, because it lets a sender create and maintain one recovery journal system for all receivers, a big efficiency improvement over N recovery journal systems. However, a receiver doesn't send RTCP RR packets describing a sent stream to all other participants, only to the original sender. This is for efficiency ... BTW, Appendix B of the MWPP guidelines document: http://www.ietf.org/internet-drafts/draft-lazzaro-avt-mwpp-coding-guidelines-01.txt Covers this topic in detail ... ------------------------------------------------------------------------- John Lazzaro -- Research Specialist -- CS Division -- EECS -- UC Berkeley lazzaro [at] cs [dot] berkeley [dot] edu www.cs.berkeley.edu/~lazzaro ------------------------------------------------------------------------- _______________________________________________ Audio/Video Transport Working Group avt@ietf.org https://www1.ietf.org/mailman/listinfo/avt
