P2P之UDP穿透NAT的原理与实现源代码，有VC实现的网络编程

vc下基于winsock2的网络嗅探器的程序。可以查看数据包的协议、源目的地址和端口以及数据及其大小-vc-based network sniffer Winsock2 procedures. Can view the data packet protocol, source and destination address and port data and the size of

使用IO完成端口异步通讯的VC源代码- 服务端程序 将客户端发来的信息发送回客户端-use IO completed port asynchronous communications source code VC-end services to the client process to the information sent back to Client

封装的Winsock控件，添加了StartServer和StopServer方法，比原来的Winsock控件有所改进。-Winsock Control package, and added StartServer StopServer methods than the original Winsock control has improved.

ARQ协议实验的实现，模拟发送方和接收方，将文件1中的数据发送到文件3，其中文件2保存中间内容-ARQ protocol implementation experiment to simulate the sender and receiver, a data file sent to the paper 3, in which the middle of the contents of the file to save two

服务器端通过socket()系统调用创建一个Socket数组后(即设定了接受连接客户的最大数目)，与指定的本地端口绑定bind()，就可以在端口进行侦听listen()。如果有客户端连接请求，则在数组中选择一个空Socket，将客户端地址赋给这个Socket。然后登录成功的客户就可以在服务器上聊天了。-Server-side through the socket () system call to create a Socket after the array (that is set to receive the maximum number of connected customers), with a specified local port to bind bind (), will be able to listen on port listen (). If the client has to connect the request, then select an empty array Socket, the client address assigned to the Socket. And then sign in the success of customers can chat on the server.

模拟netstat的功能，扫描本机当前的所有tcp,udp连接，以及开放的端口信息-Netstat simulation function, scan the machine for all the current tcp, udp connections and open ports information

测试本机的网络流量，在内存中绘图，然后以图形显示。-Test the local network traffic, in memory drawing, and then to graphic display.
