摘　　要：对具有延迟、带宽和低代价等多Q OS约束的多播路由算法进行研讨,描述了一种适应于研究Q OS多播路由的网络模型,提出一种具有多Q OS约束的动态多播路由算法(DM RAQ OS),DM RAQ OS试图有效地减少生成多Q OS约束的多播树的开销,使多播组成员能动态地加入/退出多播会晤,且不干扰现有的多播树。仿真实验结果表明,与YAM和Q OSM IC比较,DM RAQ OS具有较小的延时和较少的代价。This paper discusses the multicast routing problem with multiple QoS constraints, which may deal with the delay, bandwidth and cost metrics, and describes a network model for researching the routing problem. It presents a dynamic multicast routing algorithm with multiple QoS constraints （DMRAQoS）. The DMRAQoS attempts to significantly reduce the overhead of constructing a multicast tree with multiple QoS constraints. In DMRAQoS, a multicast group member can join or leave a multicast session dynamically, which should not disrupt the multlcast tree. Simulation results show that DMRAQoS is less in delay and cost than YAM and QoS MIC.
