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.
