摘　　要：本文比较了传统IP网络的QoS体系结构,通过分析IntServ和DiffServ两种模型的基本原理、工作方式,并指出其各自的优缺点和网络应用环境,设计了将扩展RSVP协议与DiffServ模型相结合的策略来保障大型校园网QoS的实现。仿真测试结果表明,此模型的应用可以有效地提升大型校园网络的QoS。This paper studies the QoS arichecture of the triditional IP networks. Through analyzing the basic principle and working mode of the two models： IntServ and DiffServ, the paper points out their merits and demerits as well as their network application environment, respectively. This paper presents a new model which combines the extended RSVP protocol and the DiffServ model to provide the QoS guarantee strategy of big campus networks. From the emulation test results, we can see that the application of the new model can promote the QoS characteristics of big campus networks effectively.
