A Multicasting Scheme Using Multiple MCSs in ATM Networks

Abstract

In this paper, we proposed a scheme to support multiple MCSs over a single large cluster in ATM networks, and evaluated its performance by simulation. When an ATM host requests joining into a specific multicast group, the MARS designates a proper MCS among the multiple MCSs for the group member to minimize the average path delay between the sender and the group members. This scheme constructs a 2-phase partial multicast tree based upon the shortest path algorithm. We reduced the average path delay in multicast tree using this scheme with various cluster topologies and MCS distribution scenarios, also distributed load among multiple MCSs
