摘要
对不同拓扑结构的网络进行性能参数的提取、分析和比较,得出各自的网络性能,利用仿真软件NS-2模拟星型、环型和网型3种拓扑结构,通过发送数据流获取our.tr文件.利用C++语言编写程序从our.tr文件中获取所需的性能参数信息.通过分析可知,星型拓扑结构数据传输速度快,但可靠性较低;网络拓扑结构数据传输速度慢,但可靠性最高;环型拓扑结构介于二者之间.
This paper carries on the performance parameter to the different network topology the extraction,analysis and comparison,which obtains the respective network performance.Uses network simulator version 2 to simulate the star,ring and network three kind of topology structure,gains our.tr document through the transmission to the data stream,obtains the performance parameter information which using the C ＋ ＋ language write program from our.tr document needs.The data transmission speed of star topology is quick,the reliability is lower;however,the network topology data transmission speed is slow,the reliability is highest;and the ring topology is situated between both of them.
