SIMMT-II: implementation of network simulator for IP multicast using multiple MCSs on the ATM networks

We implemented a network simulator for performance evaluation of various IP multicast schemes over ATM networks. We also described design details of the network simulator, in which necessary software modules can be added easily. This network simulator can generate various random networks, assigns multiple multicasting servers and many group members with various distribution patterns over random networks. In addition, we can apply various routing-related algorithms to the network simulator to acquire results of performance evaluation. We show the correct behavior of the implemented simulator by evaluating the performance of several recovery schemes for an impaired multicast tree in the case where some multicast servers fail.
