RTP allows multiple RTP streams to be sent in a single session but
requires each Synchronization Source (SSRC) to send RTP Control
Protocol (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 normally 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.

This document is a product of the Audio/Video Transport Core Maintenance Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
