MULTICAST ROUTING SCHEME ADEQUATE FOR VIRTUAL PATH ENVIRONMENT

The problem of accommodating multicast traffic in a virtual path (VP) environment under asynchronous transfer mode (ATM) conditions is exami ned. A network structure scheme suitable for all possible multicast co mmunications is proposed. The expected result, statistical multiplexin g effects during the accommodation of multiple multicast traffic over a VP should reduce hardware costs associated with the accommodation of multicast traffic. Multicast routing algorithms (the carrier-to-noise ratio (CNR) algorithm and the improved CNR algorithm) for an ATM netw ork environment are proposed here. The efficiency of these algorithms is tested using their basic characteristics in computer simulations.
