基于协议栈的网络监听及在仿真测试中的应用

Network Monitor Based on Protocol Stack and Application in Simulation Test

网络监听已成为仿真测试系统对被试系统运行数据进行采集的一种重要手段。随着被试系统和仿真测试系统的快速发展,需要解决网络监听对不同网络协议、操作系统和网卡的适应性问题。介绍适应于不同网络协议、操作系统和网卡的网络协议栈技术,阐述网络监听的原理,提出利用网络协议栈技术进行网络监听的两种方法,给出这两种方法的具体实现过程。通过仿真试验证明,利用上述方法能较好地完成对被试系统运行数据的采集。

For simulation test system, the network monitor becomes an important way to collect running data of tested system. The applicability of network monitor for different network protocol, operation system and network card is needed to be solved along with the development of simulation test system and tested system. This paper introduces the technology of network protocol stack which can suit different network protocol, operation system and network card, expounds the theory of network monitor, puts forward two methods of network monitor by using network protocol stack, and gives the detailed steps of two methods. The simulation experiments have proved that the methods can well complete running data collecting for tested system.
