scope:

The scope of this Recommendation is related to RTP control protocol (RTCP) handling by ITU-T H.248 media gateways (MGs) [ITU-T H.248.1]. The required MG behaviour is fairly clear for the majority of use cases. However, there are some scenarios which benefit from or even require explicit signalling indication for an unambiguous control of MG RTCP (but also RTP) traffic handling behaviour.

This Recommendation covers:

- information on the history and motivation behind RTP topologies and RTCP handling and the available ITU-T H.248 tool landscape (clause 6);

- overview tables concerning RTP topology versus RTCP handling aspects and relevant ITU-T H.248 connection models (clause 7);

- RTCP service aspects (clause 8);

- scope and limitations of RTP topology control (clause 9);

- an ITU-T H.248 package for basic RTP topology control (clause 10); and

- package independent procedures for RTP topology control (clause 11).

This Recommendation may be useful in scenarios where an MG supports multiple RTP topologies and/or multiple RTP/RTCP services which may lead to ambiguous behaviour. In these scenarios an ITU-T H.248 profile specification may use the package in this Recommendation to alleviate this behaviour.
