(WinPcap (windowspacketcapture) is a free and public network access system under Windows platform. The purpose of developing WinPcap is to provide Win32 applications with the ability to access the underlying network. Analyze the direct download address information of online streaming media, which is similar to the package of Libpcap, and supports the Win32 platform. It can be used for packet capture and network analysis. It is a packet based on Libpcap and BPF (Berkeley framing filter) model of UNIX. WinPcap is an architecture for packet capturing and network analysis on Win32 platform. It includes a kernel - centric packet filter, a low-level dynamic link library (packet.dll) and a high-level system independent Library (wpcap.dll). Why use "architecture" instead of "library"? Because packet capturing is a low-level mechanism that requires interaction with network adapters (network cards) and operating systems, and is closely related to the implementation of the network, simply using "library" can not fully express the role of WinPcap. softbar
