Hierarchically Distributed Multicast Management Architecture in ATM networks

A Hierarchical Distributed Multicast Management Architecture (HDMMA) is proposed to extend Private Network-Network-Interface (PNNI) protocol and Active Multicast Service Architecture (AMSA) to support native A KV multipoint-to-multipoint multicast (MTM) Simulation results show that the joining latency is not sensitive to the growth of both network size and multicast group size. The memory consumption in individual Physical Multicast Membership Server (PMMS) reduces significantly by using hierarchical distributed membership management architecture. In general, the proposed HDMMA with source-rooted MTM is suitable for multicast set-vice management with dense mode and has high overhead with sparse mode in large ATM-networks.
