Abstract:
Network-based functions that terminate large numbers of RTP media
streams and that offer high availability, such as session border
controllers or conference bridges, typically preserve the same IP
address towards sources of RTP media across a failover event because
it is impractical to signal a change of IP address towards large
numbers of RTP sources sufficiently rapidly to keep media
interruption intervals within acceptable limits. The need to
preserve the IP address of RTP media terminating functions across a
failover event imposes architectural requirements that can be
difficult or costly to meet, particularly in network function
virtualization environments. This document describes the problem,
outlines the key requirements for a solution, and discusses the
merits and shortcomings of various existing approaches to solving
the problem, before arguing that a new solution is needed.
