Classification: H04L,H04Q

Abstract:
An apparatus, for use in a data communication network, for searching a least cost multicast path connecting a source node and multiple destination nodes and allocating a route to the nodes in the network, which comprises:a network manager processor for initializing a configuration and status data of the network and generating initialization data;a network model processor for creating a network model for a multicast routing, based on the configuration, characteristics of a network resource and the status data passed by said network manager processor;a multicast routing processor for searching the cost optimized multicast route in response to a multicast routing request from an associated subscriber;a node processor disposed on each of the destination nodes for receiving information for the source node, a group of the destination nodes, a type of service and routing constraint conditions, and transmitting the multicast routing request through said network manager processor to said multicast routing processor; anda node interface control processor for interfacing between the destination nodes, the source node, and the network manager processor.
