摘　　要：网络服务质量Qo S在层次型网络中要求更高.从OSI参考模型的第二层与第三层出发,分析了传统的Qo S体系结构和三种Qo S模型的工作原理、优缺点以及网络应用环境.设计了将Int Serv与Diff Serv模型相结合的互补算法来保证层次型网络的服务质量.仿真结果表明,此模型能够从传输延迟、丢包率、延时抖动和网络吞吐量等多个方面提升网络的Qo S.Hierarchical IPv4 networks put forward higher requirements for the quality of service. This paper analyzes the advantages, disadvantages and the application environment of the traditional Qo S architecture based on business according to the second layer and the third layer of the OSI reference model. Then a Qo S algorithm integrated differentiated service model with integrated service model is designed to enhance the Qo S of a hierarchical network. The simulation results prove that the model can improve the network＇s Qo S in many aspects such as packet loss rate,transmission delay, delay jitter and network throughput.
