Title : Duplicating RTP Streams

Abstract:
Packet loss is undesirable for real-time multimedia sessions, but can
occur due to congestion, or other unplanned network outages. This is
especially true for IP multicast networks, where packet loss patterns
can vary greatly between receivers. One technique that can be used
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 Real-time Transport
Protocol (RTP) streams can be duplicated without breaking RTP or RTP
Control Protocol (RTCP) rules.
