Title : RTCP Extension for Third-party Loss Report

In a large RTP session using the RTCP feedback mechanism defined in
RFC 4585, a feedback target may experience transient overload if some
event causes a large number of receivers to send feedback at once.
This overload is usually avoided by ensuring that feedback reports
are forwarded to all receivers, allowing them to avoid sending
duplicate feedback reports. However, there are cases where it is not
recommended to forward feedback reports, and this may allow feedback
implosion. This memo discusses these cases and defines a new RTCP
third-party loss report that can be used to inform receivers that the
feedback target is aware of some loss event, allowing them to
suppress feedback. Associated SDP signalling is also defined.
