SSM - Source Specific Multicast

In normal IP multicast operation, numerous entities are permitted to be the source of a multicast traffic stream. SSM describes the notion of one source of traffic associated with the multicast group, as opposed to numerous. This is particularly relevant for IPTV services, where the source for the multicast group would be an individual media server. As such, when subscribers choose a particular channel, they will join the multicast group for that channel but also specify the source IP address of the appropriate media server.
