摘　　要：介绍了一种端到端的QoS架构模型:Intserv over Diffserv,研究了它的映射机制,构造了一种映射函数和网络配置,然后以服务流的吞吐量、路由器中的队列长度和分组的丢包率作为衡量参数,通过具体的仿真评估了此模型中的IntServ服务通过Diffserv区时所能获得的QoS。This paper has introduced an end to end model： Intserv over Diffserv and discussed the mapping mechanism of this model, Based on the mapping function and network configuration in this paper, we carried our simulation to determine the QoS of lntserv service that can be provided when they are run over Diffserv using goodput of applications,the queue size at the router and drop ratio of packets as the performance criteria.
