This paper proposed a new dynamic application-oriented multicast routing algorithm for replicated servers. It takes account of the probability that multicast members join or leave the multicast connection and adds into the cost function of the multicast routing tree. By doing so, the members are intended to be designed as the leaves of the multicast tree. According to the cost function, it can select the minimum cost function tree. The numeric simulation shows that the algorithm can use network resource efficiently.
