Abstract:
1. A relay multicast system (RMS) comprising: a plurality of multicast feeders, each generating a session join request signal, receiving same class peer list information, and relaying multicast data transmission/reception; and a session manager managing session information of the multicast feeders and generating the same class peer list information in response to the session join request signals, wherein a unique multicast feeder in a local multicast domain selects a peer multicast feeder from the same class peer list information and communicates with the selected peer multicast feeder by negotiating a hop-by-hop channel, and wherein, when each of the multicast feeders joins a session, if the multicast feeder receives the same class peer list information the multicast feeder determines whether the multicast feeder is the unique feeder in the local multicast domain, and if the multicast feeder is the unique feeder in the local multicast domain, the multicast feeder selects the peer multicast feeder from the same class peer list information and communicates with the selected peer multicast feeder by negotiating the hop-by-hop channel.
