3.5.6 IPv4 SSM information
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 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).
