ABSTRACT:
A method for multicast routing for a telecommunications network comprising a plurality of communication nodes interconnected by multiple paths, for the establishment of a multicasting connection between a source node and a plurality of destination nodes, in which the destination nodes are informed that a multicast connection request is arriving from a particular source. Each destination node then sends a connection request to the source, and these requests are processed and relayed by each node within the network. The requests are propagated from node to node until they reach the source node, carrying the information on the cost accumulated along the path. Finally, the source node, having received the information on the costs of the possible paths, selects the path which has a satisfactory cost.
