基于MAC层帧捕获及协议分析的技术研究

摘要

This paper introduces the principle and the method that catchEthernet physics frame by Controlling directly net work adapter in MAC sub-layer, then explain how to analysis and understand the information included physics frame according to protocol criterion, and introduce a technique of catching continually the information frame and getting property from protocol unit. At last, it discusses how to design the application software of network management and control.%本文首先介绍在MAC子层直接控制网络适配器捕捉以太网络物理帧的原理与方法，然后说明如何根据协议规范对物理帧所包含的信息进行分析和理解，接着介绍连续捕捉信息帧并从中抽取协议包的特征的技术，最后讨论了网络管理及控制的应用软件的设计.
