Multicast routing strategies for zoned VP-based ATM networks

In ATM networks, the concept of virtual path (VP) greatly simplifies cell processing in switches. The virtual channel connection (VCC) can be more quickly and efficiently established by good strategies of resource management. The method of constructing virtual path and the strategies of managing and allocating resources greatly affect the performance of the system operation. We propose a new architecture and the corresponding methods of constructing virtual paths; various methods and strategies, such as bandwidth control, rerouting, resource management, and fault recovery, are studied (Lee and Shie 2000). This paper focuses on multicast routing and analyzes some algorithms for this model. Simulation results show the good performance in bandwidth utilization, blocking probability, and loss probability
