Organization: ITU-T
Publication Date: 1 February 2010
Status: active
Page Count: 26
scope:

This Recommendation defines several H.248 packages that relate to RTCP flows that terminate at or pass though the MG.

The RTCP Source Description package maps information appearing in sent and received RTCP Source Description (SDES) packets into H.248 statistics. Auditing these statistics allows the MGC to gain a better understanding of the RTP end-systems and intermediate systems that participate in an RTP session.

The Received RTCP package maps information appearing in received RTCP Sender Report and Receiver Report packets into H.248 statistics. By auditing these statistics, the MGC can collect performance and QoS metrics, measured by the remote participants of the RTP session.

The RTCP Feedback Message package allows the MGC to be notified when the MG receives RTCP feedback messages, and to instruct the MG to send such messages. RTCP feedback messages are used by RTP Audio Visual Profiles with feedback extensions (see [IETF RFC 4585]).
