Abstract:
A straightforward approach to provide protection against packet
losses due to network outages with a longest duration of T time units
is to simply duplicate the original packets and send each copy
separated in time by at least T time units. This approach is
commonly referred to as Time-shifted Redundancy, Temporal Redundancy
or simply Delayed Duplication. This document defines an attribute to
indicate the presence of temporally redundant media streams and the
duplication delay in the Session Description Protocol.
