Source Specific Multicast
Source Specific Multicast (SSM) is a datagram delivery model that best supports one-to-many applications,
also known as broadcast applications. SSM is a core network technology for the Cisco implementation of IP
multicast targeted for audio and video broadcast application environments.
For the SSM delivery mode, an IP multicast receiver host must use IGMP Version 3 (IGMPv3) to subscribe
to channel (S,G). By subscribing to this channel, the receiver host is indicating that it wants to receive IP
multicast traffic sent by source host S to group G. The network will deliver IP multicast packets from source
host S to group G to all hosts in the network that have subscribed to the channel (S, G).
SSM does not require group address allocation within the network, only within each source host. Different
applications running on the same source host must use different SSM groups. Different applications running
on different source hosts can arbitrarily reuse SSM group addresses without causing any excess traffic on the
network.
