基于OPNET的网络建模仿真分析
|
摘要
随着网络规模的不断扩大,如何扩建网络成为网络规划设计的难题。网络仿真技术成为网络规划设计可靠的定量依据,能够验证实际方案或比较多个不同的设计方案。先对OPNET仿真软件及网络模型结构进行介绍,并搭建出原网络模型和两种方式扩展后的网络模型。对网络进行仿真,获得扩展前后的网络延时、排队延迟、吞吐量和利用率网络性能的参数曲线,并对仿真结果进行了分析,选出最佳扩展的设计方案。
With the continuous expansion of network scale,how to expand the network becomes a difficult problem in network planning and design. Network simulation technology has become a reliable quantitative basis for network planning and design,which can verify the actual scheme or compare many different design schemes. Firstly,the OPNET(Optimized Network Engineering Tool) simulation software and network model structure are introduced,and the original network model and two extended network models are established. The parameters of network delay,queue delay,throughput and network utilization are obtained by simulation. The simulation results are analyzed and the best extended design scheme is selected.
