一个高性能的网络数据包处理架构，利用WinpkFilter可以利用应用层函数直接对数据包进行处理，甚至可以在应用层函数sleep（）延缓数据包发送(WinpkFilter is a high performance packet filtering framework for Windows that allows developers to transparently filter (view and modify) raw network packets with minimal impact on network activity without having to write low level TDI or NDIS driver code. WinpkFilter is more than just a firewall development kit for Windows. With WinpkFilter you can make an application that inserts itself into the Windows network stream: custom firewall solution, internet connection sharing (NAT), IP shaper, VPN and many other low-level network solutions completely in user-mode using your favorite development environment: Visual C++, Visual C#, Delphi, Visual Basic, C++ Builder and etc. Using WinpkFilter requires no experience in kernel mode programming on your behalf since WinpkFilter provides you with powerful user level API. However, if you need to implement your solution (to achieve better performance) in kernel mode you can use well-documented raw IOCTL interface as well. )
