摘　　要：针对多媒体通信中的可靠性问题，提出了一种基于可靠性检验的可靠多播路由算法，使得用于可靠多播通信的网络资源最小。该算法针对一棵给定的、未考虑可靠性的初始多播树，分别计算源节点到每个多播节点路径上的可靠性，如果该可靠性不能满足相应的可靠性要求，则修改或改变多播树中源节点到此多播节点的路径，使其满足相应的可靠性要求。In this paper, a reliable muhieast routing algorithm based on reliability test is proposed in accordance with the problem of reliability in the multimedia communication, which minimizes the network resource utilization for a reliable muhieast. According to a given initial multieasting tree without consideration of reliabflty, the reliability of the path between the source and a selected multieasting member can be calculated respectively. If the corresponding reliability requirement of this path isn＇t satisfied, the path can be modified or changed according to the algorithm, and the corresponding reliability requirement of the path can be satisfied.
