用于网络仿真中的流量产生与packet之间依赖关系的判断与清除，有多种仿真模式可以使用，需要在linux环境下使用，以文档的形式输出仿真结果。(There are many kinds of simulation models that can be used to estimate and eliminate dependencies between traffic generation and packet in network simulation. They need to be used in Linux environment and output simulation results in the form of documents.)
