The XRBLOCK working group is chartered to work within this framework, evaluating proposals for report block definitions containing new metrics. The group will follow the guidelines established in RFC5968, "Guidelines for Extending the RTP Control Protocol (RTCP)" and RTP Monitoring Architecture being developed in the AVTCORE working group. The group will consider the guidelines for performance metric development currently being discussed in the PMOL working group.
