基于OPNET的城域间FTP服务建模与性能分析

FTP service modeling and performance analysis of metropolitan based on OPNET

介绍了网络仿真技术的概念及OPNET网络建模的基本过程,设计一个城域间FTP服务网络模型,并分别在有链路背景流量和无链路背景流量环境下对该网络模型进行了仿真。结果表明:链路背景流量对链路的利用率及FTP上传下载的响应时间均有较大影响,链路背景流量越大,链路利用率越高,链路负载越重,FTP上传下载响应时间越长。

The concept of network simulation technology and the process of OPNET network modeling were introduced,FTP service network model of metropolitan was designed,and the network model under the conditions with linking background traffic and without linking background traffic was simulated.The result shows that the linking background traffic has significant impact on its utilization and the response times for FTP upload and download.The larger the linking background traffic,the higher the linking utilization and heavier the linking load.The response of FTP upload and download will be much longer.The analysis results have great reference value for actual FTP network planning and design.
