基于opnet的胖树多播网络仿真，主要为多播算法的仿真，程序较完善(Opnet fat tree multicast network simulation, primarily for multicast algorithm based simulation program better)

服务器端代码··可以跟客户端自由通信··(Server-side code can be freely client communications)

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. Locate the server s IP address and protocol port number 2 creates a socket 3 connections need to determine arbitrary, unused port allows TCP to choose a 4 and the socket server connections 5 using appli)

这是一本关于IOCP模型原理及其功能介绍的文章。对于做大型服务器很有帮助(This is a book about IOCP model and the function introduction article. For large server help )

基于HTTP协议的支持断点续传的下载软件源码(HTTP protocol support for HTTP-based download software source)

说明：  根据域名获得IP地址列表 根据域名获得IP地址列表(under the name list of IP addresses under the domain of IP address list)

检测NAT类型的客户端，程序中指定了服务器IP地址，用户可以自行修改(Detect NAT type of the client, the program specifies the server IP address, the user can modify)

Windows的网络流量速度检测。使用MFC作为开发平台。(A net speed spyer using MFC platform .)

网络程序，判断是否连接至外网，主要是读取内容来判断(Network program, to determine whether to connect to the external network, is read content to determine)

局域网 实现文件的数据传输 传输进行了 文件属性的 处理， 接受后文件属性不变！(LAN file transfer data transfer carried out the deal with file attributes, file attributes unchanged accepted!)
