Abstract
WinPcap system is a powerful package of network data acquisition,provides programmers with a standard set of network packet capture interface,which directly act on the network adapter,access to the data link layer of the data,and can capture all of the data link layer packets.This paper outlines the internal structure of WinPcap,a brief description of the WinPcap packet capture implementation and a detailed analysis of the realization of WinPcap packet capture process.
