Abstract:
RTP allows multiple media streams to be sent in a single session, but
requires each Synchronisation Source (SSRC) to send RTCP reception
quality reports for every other SSRC visible in the session. This
causes the number of RTCP reception reports to grow with the number
of SSRCs, rather than the number of endpoints. In many cases most of
these RTCP reception reports are unnecessary, since all SSRCs of an
endpoint are co-located and see the same reception quality. This
memo defines a Reporting Group extension to RTCP to reduce the
reporting overhead in such scenarios.
