Abstract:
In order to overcome the lack of the current DiffServ multicast proposals, this paper proposes a new approach of multicast in DiffServ networks, which not only solves Neglected Reserved Sub-tree(NRS), scalability and heterogeneous QoS problem, but also improves link utilization ratio through using link resource allocation strategy. In addition, it can alleviate inter-class fairness problem by integrating with proper multicast routing algorithm.

摘要: 针对已有区分服务多播模型中存在的不足,提出一种基于区分服务网络的QoS多播模型。该模型在解决非预留资源子树问题、可扩展问题、异构问题的同时,根据多播的树型传输特点采用基于链路的资源分配策略,从而提高了网络的资源利用率,与QoS多播路由算法集成可以有效地解决服务类间的公平性问题。
