Technical Summary
This document specifies an extension to the Real-time Transport
Control Protocol (RTCP) to use unicast feedback to a multicast
sender. The proposed extension is useful for single-source multicast
sessions such as Source-Specific Multicast (SSM) communication where
the traditional model of many-to-many group communication is either
not available or not desired. In addition, it can be applied to any
group that might benefit from a sender-controlled summarized
reporting mechanism.
Working Group Summary
There is interest in this work both with AVT and the MBONED
community, and solid consensus to publish the draft.
Document Quality
The draft fills an important gap and is needed to deployed SSM-based
IPTV systems. As a result there is strong interest in seeing it
done, and implementations are expected.
Personnel
Colin Perkins is the proto document shepherd. Cullen Jennings is the
responsible area director.
