NS2条件网络性能分析实践

Network Performance Analysis Using NS2

通过对网络性能进行分析,可以有效整合、充分利用现有的网络资源,完善网络结构,使现有网络达到最高效能。NS2作为流行的网络仿真工具,具有仿真结果真实、构件丰富、可扩展性强等特点,但是其中并未集成性能分析工具,无法对网络的关键性能指标进行测量分析。本文通过编写性能分析脚本对NS2仿真结果进行处理,最终以直观的方式展现了仿真过程中网络性能的变化趋势,为进一步的研究提供了基础。

Network performance analysis can effectively integrate,and make full use of the existing network resources. It also improves the network structure and brings out the highest performance of the existing network. NS2 as a popular simulation network simulation tool, it has real simulation data results, rich network component and high scalability, but it doesn＇t contain performance analysis component,so it is unable to measure key network performance indicators. This paper describes bow to process NS2 simulation results with performance analysis script, and makes an intuitive way to show the trend of network performance during the simulation. It provides a basis for further performance analysis.
