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. )

说明：  程序实现了一个简单的网络版的掷骰子，一个服务器端，另一个客户端。(Program implements a simple network version of the dice, a server-side, another client.)

CPing依据ICMP协议实现, 可解析域名和IP, 可设置发包数量,统计丢包率(CPing based on ICMP protocol implementation can resolve domain names and IP, you can set the number of contracting, statistical packet loss rate)

Pop3客户端接收信件的整个流程： 1。连接到pop3服务器（默认端口110） 2。发送用户名（user） 3。发送密码（pass） 4。查询当前邮箱状态（stat） 5。查询服务器上所有邮件UID列表（UIDL） 6。查询本地所有邮件的UID列表，从而罗列出新邮件列表（本地UID列表是POP3客户端记录在日志文件中的） 7。对所有新邮件查询其大小（LIST） 8。下载所有新邮件（RETR）利用List提供的邮件大小信息 9。如果有必要，对所有新邮件标志为删除（DELE） 10。结束对话（QUIT） 11。解析本地下载邮件。(Pop3 client receives the entire flow of letters: 1. Connect to the pop3 server (default port 110) 2. Send user name (user) 3. Send password (pass) 4. Query current mail status (stat) 5. Query server UID list of all messages (UIDL) 6. Query local UID list of all messages, which set out the new mailing list (local UID is a POP3 client list recorded in the log file) 7. For all new e-mail inquiries about their size (LIST) 8. Download all new messages (RETR) to use List of information provided by message size 9. If necessary, for all new signs for the delete message (DELE) 10. The end of the dialogue (QUIT) 11. Analysis of local download your mail.)
