网络仿真可以为网络规划设计和网络性能分析提供客观、可靠的定量依据,因此可以减少网络的建设周期和新协议开发周期。本文利用OPNET网络仿真工具,对排队论模型M/M/1进行仿真,将仿真结果和排队数学结论进行了分析比较研究,同时对四种常用的队列算法FIFO、CQ、PQ、WFQ进行仿真,分析比较了各自对时延的影响及可提供的QOS服务。
Network simulation can provide an objective and reliable quantitative basis for network planning and network performance analysis, thus reducing the network construction period and the new protocol development cycle. In this paper, we use the OPNET network simulation tool to simulate the queuing theory model M / M / 1, and analyze and compare the simulation results and the queuing mathematics conclusion. At the same time, we simulate four common queue algorithms FIFO, CQ, PQ and WFQ, Analysis and comparison of their impact on the delay and can provide QOS service.
