摘要: 提出一种适合于DiffServ网络的QoS多播路由算法PQMRD,它针对组成员不同类别的QoS请求采取不同的路由策略来选取路径,同时进行分类的接纳控制和资源预留。实验结果表明,PQMRD缓解了现有多播算法中因所有业务选择相同路径而引起的服务类间的不公平性问题。

Abstract: A QoS multicast routing algorithm for DiffServ networks called PQMRD(Per-class QoS Multicast Routing in DiffServ networks) was proposed. It used different routing strategy to select route in terms of different QoS requirement; in addition, admission control and resource reservation were performed while selecting route. It is proved by the simulation result that inter-class unfairness problem is alleviated.

Key words: multicast, DiffServ, Quality of Service, inter-class fairness
