NS网络仿真技术及其结果输出和分析

Output and analysis of the results from NS network simulator

为了在仿真环境下对网络协议进行性能评价,必须对仿真结果进行有效的分析和处理。介绍了NS网络仿真器的两层体系结构,描述了跟NS相关的几个常用工具,然后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。

In order to evaluate the performance of network protocols in simulating environment, the simulating results must be analyzed and processed carefully. The paper firstly introduces the hierarchical architecture of NS Network simulator, and analyzes some tools. Finally, it illustrates how to program to evaluate the protocols.
