Abstract:

This paper analyzes the main elements in NS network simulator, makes a detailed view of dataflow management in a link, a node, and an agent, respectively, and introduces the information described by its trace file. Based on the analysis of transportation and treatment of different packets in NS, a dataflow state machine is proposed with its states exchange triggering events and a dataflow analyzer is designed and implemented according to it. As the machine state functions, the analyzer can make statistic of total transportation flux of a specified dataflow and offer a general fluctuation diagram. Finally, a concrete example is used to test its performance.

分析了NS(network simulator)仿真器的主要元素, 介绍了它的结点、链路以及代理对数据流的处理方式和流程, 描述了在脚本文件中识别和采集数据流的方法.基于仿真结果表示的方法, 得到了解析数据流的状态, 并构造了相应的转移事件和状态机, 实现了针对指定流类型统计网络中任意结点流量的分析器, 在一个NS应用中, 通过分析器产生了统计结果, 证明了该设计的可行性和有效性.
