摘　　要：论文讨论了具有延迟、带宽和低代价等多QoS约束的多播路由算法,提出了适应于研究QoS多播路由的网络模型,并给出了一种具有多QoS约束的动态多播路由算法,分析了算法的复杂度。仿真实验证明,该算法是稳定有效的。它能够在满足多约束的情况下,使多播树的代价优化。This paper discusses the multicast routing problem with multiple QoS constraints,which may deal with the delay, bandwidth and cost metrics, and presents a network model for researching the routing problem. It proposes a dynamic multicast routing algorithm with multiple QoS constraints. Simulations are showed to prove that the algorithm is effective and stable. It can minimize the multicast tree cost without violating the multi- constrained.
