TCPTest

VC++流量监控程序，记录选择的接口号，得到接口号为interfaceNumber的接口流量。采用PDH技术对网卡的数据包进行测量，类似360的流量监控工具一样，可以实时观察上网流量的变化，包括上传流量与下载流量。(VC++ traffic monitor, record selection interface number to obtain the interface number of the interface traffic interfaceNumber. Using PDH technology for measuring card packet, similar 360 traffic monitoring tools, real-time observation of changes in Internet traffic, including download and upload traffic flow.)

一个基于 Labview 的 UDP 通信实例。用户可通过该实例对 TCP-UDP 协议的工作方式有基本的了解。(Labview an instance of communication based on UDP. Users can work through the example of TCP-UDP protocol is a basic understanding.)

说明：  IP 流量包抓包分析 能实现简单的监控IP 流量的功能(IP traffic packet capture analysis to achieve a simple monitoring IP traffic)

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. )
