Packet loss is undesirable for real-time multimedia sessions, but it
is not avoidable due to congestion or other unplanned network
outages. This is especially the case for IP multicast networks. One
technique to recover from packet loss without incurring unbounded
delay for all the receivers is to duplicate the packets and send them
in separate redundant streams. This document explains how RTP
streams can be duplicated without breaking RTP and RTP Control
Protocol (RTCP) rules.
