摘　　要：介绍了校园网现状及OPNET Modeler的集成开发环境,对江苏师范大学科文学院现有校园网主要的网络应用响应时间及重要的网络性能指标进行了仿真,同时对加载视频点播业务的校园网进行仿真,找出影响校园网性能的"瓶颈",提出升级改造方案,仿真结果验证了方案的可行性.The current situation of campus networks and the integrated development environments of OPNET Modeler are introduced.Then simulations for network application response time and network performance index at Jiangsu Normal University Kewen College are conducted.By comparing the simulation results of campus networks at the regular usage and at the one with heavy usage of video-on-demand(VoD)service,the“bottleneck”of campus network performance is found.Finally,an update plan for campus networks is proposed,simulated,and evaluated.
