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.)

模拟路由器功能，简单的c++程序代码，可以实现。(Simulation router function a simple c++ code, can be achieved.)

编写程序，实现基于ARP协议获取本局域网内全部活动主机MAC地址与IP地址对应关系列表，要求使用Winpcap，手动封装ARP数据包，并实现ARP响应数据包的接收和解析。(programming, ARP-based LAN access to the activities of all MAC address and IP address correspondence list, require the use of Winpcap, manual Packaging ARP packets, and achieve ARP response data packet reception and analysis.)

界面清爽VB版高级专业防火墙 Ver 2.0.3 源代码，非常棒,强烈推荐！(VB version of the interface refreshing senior professional firewall Ver 2.0.3 source code, great, highly recommended!)

程序记录并显示了数据报从源端机器传送到目标机器的过程中所经过的路由器的IP地址，并且记录了数据报到达每个路由器所需要的时间。认真观察到达每个路由器的时间有什么区别，从而熟练掌握traceroute的工作原理和ICMP报文协议。　(The program records and displays the IP addresses of routers through which the datagram sent from the source client machine to the target machine , and the recording of the data packets arrive at the time required by each router . )

使C++语言编程，实现双机在联网条件下通过IP地址实现通信。(With C++,we can make two computers commnicate with each other when they are on the Internet.)

这是一个简单的socket编程例子，非常适合刚接触socket编程者。程序简单、可用、易于理解。是个很好的socket范例。(A simple socket programming examples. Suitable for beginners. Program is simple, available, easy to understand. Is a good example of socket programming.)

当遇到网上下载的很多歌txt文件电子书，或程序生成的多个txt，可根据文件名合并成一个，自己写的，大方分享(Txt file, e-book experience online download many songs, or program generated txt, based on the file name to be merged into one, write your own, and generous sharing)

多协议文件传输c/s网络应用设计与实现,程序用 TCP/UDP 两个协议模拟多协议服务器。首先服务器端要将两种协议的套接字创建好，并且监听 TCP 端口的连接。必要时使用select函数来进行多连接处理和非阻塞处理。而客户端直接可以按照发送的地址和端口号来进行通讯。 首先要运行服务器端，服务器会监听 TCP 端口。然后运行客户端，根据事先设定好的 IP和端口，就可以进行连接传输数据了。 程序实现的关键步骤： 以TCP协议为例 服务器端： 1.创建套接字；2.绑定端口；3.进入无穷的循环；4.接收请求；5.处理请求；6.应答。 客户端： 1.找到服务器的IP地址和协议的端口号；2.创建套接字；3.确定连接需要任意的，没有使用的端口号允许TCP去选择一个；4.将套接字和服务器连接；5.使用应用层协议和服务器交互；6.关闭连接。 (Multi-protocol file transfer c/s network application design and implementation of programs simulate multi-protocol server with TCP/UDP both protocols. First socket server to create a good two protocols, TCP port and listens for connections. If necessary, use the function to handle multiple connections and non-blocking treatment. And the client can follow directly address and port number to communicate. First run on the server side, the server listens on TCP port. Then run the client, according to pre-configured IP and port, you can connect the data transmission. The key step program implementation: In TCP protocol as an example Service-Terminal: 1. Create a socket 2 bound port 3 enter an infinite loop 4. receiving a request 5. processing requests 6 response. Clients: 1.
