The Research of Multicast Routing Algorithm in Network Based on QoS

At present, the research of multicast routing algorithm are mostly aimed at the unrestrained multicast routing question and a limited multicast routing problem, at the same time, use some method such as heuristic. In this paper, combine the features of QoS multicast routing algorithm and the genetic algorithm, a QoS multicast routing algorithm based on genetic algorithms was improved. Through experiments we can see, this algorithm can choose a network routing which is not accurate of state information better, at the same time, it can maintain a high succeed rate.
