摘　　要：QoS路由为具有QoS要求的应用寻找满足条件的网络路径,同时优化网络的资源利用率.IntServ/DiffServ混合网络模型很好的结合了IntServ网络每一流的处理能力和DiffServ网络良好的可扩展性的优点.本文提出了一种在这种混合网络模型中提供带宽—延时保证服务的QoS路由算法,对于在网络中传送具有带宽—延时要求的应用服务是一个可行的解决方案.通过仿真实验,验证了算法的有效性.QoS routing finds the network path that meets the QoS requirement of the application and optimize the utilization of the network resource. The mixed IntServ/Diffserv network model has well combined the per-flow processing ability of IntServ network and the well sealability of Diffserv network. A bandwidth-delay constrained QoS routing algorithm in the mixed network model is proposed in this paper. It is a feasible scheme to deliver applications with requirements of bandwidth and delay in the networks. Experimental results show that the proposed algorithm has good performance.
