针对校园网扩容后的业务、流量分配问题,分析了网络仿真技术和常用的网络仿真软件,并利用仿真软件OPNET规划建立了连通两校区的校园传输网仿真模型.同时主要研究了服务质量(QoS)中的区分服务模型,仿真实现了不同队列策略机制,并针对校园网的QoS进行不同策略下的性能测试,得到仿真结果,找出影响校园网传输性能的主要因素,在此基础上制定出一种基于组合策略的校园传输网QoS设计方案.
This paper analyzes the network simulation technology and the commonly used network simulation software for the business and traffic distribution after the expansion of the campus network, and uses the simulation software OPNET to plan and establish the campus transmission network simulation model which connects the two campuses. At the same time, ), The different service strategy is implemented by simulation, and the performance test under different strategies is carried out according to the QoS of campus network. The simulation results are obtained to find out the main factors affecting the transmission performance of campus network. Based on this, A Campus Network QoS Design Based on Combination Strategy.
