摘要
互联网是一个庞大的、复杂的、开放的网络集合。深入了解和优化网络性能并不是一件容易的事。为了方便网络管理者对网络进行管理,探讨了NS-2仿真平台体系结构、构建环境和仿真流程,提出了采用NS2网络仿真器建立网络模拟场景来获得网络性能参数的方法,通过分析NS2网络仿真过程产生的记录文件,利用awk、gnuplot等工具获得网络的封包遗失率(Packet Loss Rate)、端到端的延迟(End-to-End Delay)、吞吐量(Throughput)等性能指标呈现了模拟结果。实验表明利用网络仿真求解网络性能参数具有直观可靠、成本低、灵活可靠、避重就轻、易于比较等优点。通过实例分析验证了该方法的有效性。
The Internet is a huge,complicated and open network.Understanding and optimizing the network performance is not an easy task.In order to make easier for mangers to manage the network,discussed NS2 simulation platform architecture,environment and simulation process.Then,used the NS2 to simulation network scenarios to obtain the network perfomance parameters.Through the analysis of NS2 network simulation process to produce records,use the awk,gnuplot and other tools to obtain the network performance parameters.Experiments show that using NS2 to get network performance parameters has advantages,such as intuitive,reliable,low cost,flexible and reliable,easy to compare.From a example,testing and verifing this method is useful.
