In a large RTP session using the RTP Control Protocol (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
signaling is also defined.
