摘　　要：为了实现VoIP端到端的QoS,本文首先介绍了两种已有的体系结构存在的不足,并在此基础上给出了一种基于集成服务模型的架构,研究了它的QoS保证机制。然后,构造了一种映射函数和网络配置,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VoIP服务在此模型中所能获得的QoS。In order to support end-to-end QoS of VoIP, the disadvantages of two existing architectures are introduced , a new model based on integrated service is proposed based on them, and the QoS guaranteed mechanism of this model is discussed. Based on the mapping function and network configuration, the paper then carried a simulation to determine the QoS of VoIP service that can be provided when they are run over this model using throughput of applications, the queue size at the router and drop ratio of packets as the performance criteria. 1
