ABSTRACT:
Disclosed is a cost minimized multicast routing algorithm, that can be used for heterogeneous applications in ATM networks. In routing multipoint information flows over ATM VP/VC networks, the algorithm generates near optimal multicast tree based on the delay requirements of services, link costs and path overlapping effects for resource saving and quality-of-service satisfying purposes. This invention uses the virtual destination node in order to find the multicast route that maximizes the overlapping effects of the path between multiple destinations, thus minimizes the number of links and switches used in the multicast communications. Also, multicast tree branching occurs as near as possible to the destination nodes so that the overlapping effects of the multicast route can effectively reduce the network resource consumption.
