Analysis of a Resequencer Model for Multicast over ATM Networks

Multicast delivery saves bandwidth and offers logical addressing capabilities to the applications. The receivers of a multicast group need to differentiate cells sent by different sources. This demultiplexing requirement can be satisfied in an ATM environment using multiple dedicated point-to-multipoint virtual channel connections (VCs), but with certain shortcomings. This paper discusses an alternative resequencing model to solve this problem. It scales well in large networks. Three resequencing methods are are developed and simulation results reported. The strategy is useful for applications spanning large regions where it is desirable to mix streams of cells from different bursty sources onto the same virtual channel.
