A reliable multicast routing algorithm based on reliability test in multimedia communication

A reliable multicast routing algorithm based on a reliability test is proposed for the problem of reliable multicast routing in multimedia communication; it minimizes the network resource utilization for a reliable multicast. For a given initial multicast tree, the reliability of the path between the source and a selected multicast member can be calculated; if the corresponding reliability requirement of this path is not satisfied, the path can be modified or changed according to the algorithm, and the corresponding reliability requirement of the path can be satisfied.
