基于WinPcap的网络监测系统设计及协议分析

Software desigh and protocol analysis for network monitor system based on WinPcap

网络监测是网络管理、安全和控制的前提,为了深入研究网络监测理论和应用开发技术,探讨了目前流行的WinPcap网络监测理论及其应用系统设计,基于Visual C++设计了一个网络通信监测系统,实现了典型的网络监测管理功能,并对系统通信协议数据包进行了基本的分析。

Network monitoring is the key to network management, security and control. In this paper, the theory and relevant application technology of the industry-standard windows packet capture library （WinPcap） is introduced in detail for further research on the lucubration of network monitoring and the design of its application system. A Visual C＋ ＋ based network monitoring system which is proved to be effective in the realization of typical network monitoring is designed and three basic protocols （MAC Ethernet, IP and UDP） are analyzed.
