针对遗传算法应用干服务质最(QoS)组播路由时运算时间长的问题，提出一种基于集群路由器的并行遗传算法，并对集群路由器的体系结构加以改进，使其适用于该并行遗传算法的运行。-lity (QoS) multicast routing computation time long when prGenetic algorithm is used to dry the service quaoblems is proposed based on a cluster of the router parallel genetic algorithm, and the system structure of cluster router to improve it, make it applies to the operation of the parallel genetic algorithm.
