>   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 certain cases where
>   it is not possible to forward feedback reports, and this may allow
>   feedback implosion.  This memo defines a new RTCP third-party loss
>   report that can be used to inform receivers that a feedback target is
>   aware of some loss event, allowing them to suppress feedback.
>   Associated SDP signalling is also defined.
