This document specifies an extension to the Real-time Transport
Control Protocol (RTCP) to use unicast feedback to a multicast
sender.  The proposed extension is useful for single-source multicast
sessions such as Source-Specific Multicast (SSM) communication where
the traditional model of many-to-many group communication is either
not available or not desired.  In addition, it can be applied to any
group that might benefit from a sender-controlled summarized
reporting mechanism.  [STANDARDS TRACK]
