摘要： 为了在仿真环境下对网络协议进行性能评价，必需对仿真结果进行有效的分析和处理．介绍了ｎｓ的两层体系结构及安装过程，描述了ｎｓ的跟踪和监视机制，并在分析ｎｓ的跟踪和流监视输出格式的基础上讨论了仿真结果的处理．除ｎｓ提供的标准输出外，还以实例说明了如何根据自己的需要在仿真脚本中对数据进行处理，只输出感兴趣的结果．

Abstract: In Order to evaluate the performance of network protocols in simulating environment, we must analyze and process carefully the simulating results. The paper firstly introduces the hierarchical architecture. and how to install us. Then we analyze the mechanism of trace and monitor, and discuss how to post-process the simulating results. Finally, we illustrate how to program to evaluate the protocols.
