Packet Capture and Analysis Based on WinPcap
Abstract：With the network security issues become more serious, the procedures for packet capture and analysis are designed based on the WinPcap. The program can view the card and the data flow through the network card, moreover, can accomplish the packet capture and filtering and analysis these data etc. The operation of system is simple, and can clearly view packet protocol information captured. So it is of great significance for the study of the Ethernet protocol and Ethernet protocol applications.
