基于FTP协议网络流量模拟的设计与实现

针对网络实验室中难以实现与真实网络环境一致、需要进行网络流量模拟的问题，提出了一种基于FTP协议的网络流量模拟方案。基于FTP协议特点和网络流量模拟需求，详细分析了网络流量模拟系统的架构、运行拓扑结构，设计了FTP流量的生成算法。通过实验证明，实现的模拟系统可以对模拟流量的发送速度和时长进行设定，而且可以随时进行更改，满足了虚拟网络流量的要求，为网络安全试验提供了模拟的网络测试环境。

Design and Implementation of Network Traffic Simulation Based on FTP

For the difficult to achieve in the laboratory network is consistent with real network environment and the need for network traffic simulation, a network traffic simulation resolution is proposed based on FTP protocol. Based on the characteristics of the FTP protocol and the needs of the network traffic simulation, the structure and the operation of the network were analyzed in detail. The network topology, traffic simulation system was also designed based on FTP traffic generation algorithm. The experiments showed that the simulation system could achieve transmission speed and duration of the flow simulation set and it, could be changed at any time to meet the requirements of the virtual network traffic.
