摘　　要：提出了一种解决QoS限制代价优化问题的分布式组播路由算法，分析和仿真表明本算法和以前的几种算法相比，具有QoS要求严格时成功率高，代价优化、性能稳定的特点。算法的这些特点使其特别适合于因特网上对QoS要求严格的宽带多媒体应用。This paper proposes an efficient distributed multicast routing algorithm that can always construct a QoS-constrained sub-optimal cost multicast tree if such a multicast tree exists. Analyses and simulations have been done to show that the algorithm has better performance than some other existing algorithms, especially under a tight QoS constraint, in terms of success rate, tree cost and stability. The characters above make the algorithm fit well the broad-band multimedia applications in the wide area networks which have a strict QoS requirement.
