用来通过HTTP协议下载的程序，支持断点续传和多线程下载(Used to download the program through the HTTP protocol, support HTTP and multi-threaded download)

说明：  务器端基于select I/O模型。为防止程序界面阻塞，有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数，不过其利用率很高，可用于远程目录交换，请求文件大小，创建若干线程来下载文件。文件传输有上传和下载,还有对等传输，这个项目中，传输文件具体指下载。(Client server based on select I/O model. Programming interfaces in order to prevent obstruction, there is a sub-thread for receiving socket and select which treatment. There is only one client thread function, but its utilization very high, can be used for remote directory exchange, request the file size, create a number of threads to download the file. File transfer are uploading and downloading, as well as peer-to-peer transmission, this project, the specific means to transfer files to download.)

一个通过socket与WEB建立通讯连接的VC程序。(through socket with a Web link in the establishment of communication procedures VC.)

UDP方式双网冗余程序，一网卡断开，另一网卡自动连接，从而保证通讯正常(UDP mode dual-network redundancy procedures, disconnect a network card, another card to connect automatically to ensure the normal communication)

计算机网络 多播 用C++编写 绝对可以用。。。。(计算机网络多播)

wsk是win7上取代tdi驱动进行网络编程的技术，程序对wsk的接口进行封装，可以像应用层一样进行socket编程。(wsk is substituted on win7 tdi driven network programming techniques, procedures for wsk interface package, socket programming can be the same as the application layer.)

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)

一个通过网络高速传输文件的控件： 具有以下特点 1.有高速数据传输功能，超过了Winsock控件的吞吐量 2.入校验功能，满足大数据包的收发，理论上不限数据尺寸 3.加入防错代码，提高了接口鲁棒性(through a network of high-speed transmission of documents, the controls : one with the following features. A high-speed data transmission functions Controls over the throughput of Winsock 2.- Check function and meet large data packet transceiver, Theoretically Open-data size 3. to prevent the wrong code, improve the robustness Interface)

编制程序，监控网络，捕获一段时间内网络上的IP数据包，按IP数据包的源地址统计出该源地址在该时间段内发出的IP包的个数，将其写入日志文件中或用图形表示出来（建议用图形表示出统计结果）。(Program monitoring network, a period of time to capture IP data packets on the network, according to the source address of the IP packet statistics of the number of the source address is issued in the time of the IP package, written into the log file or graph out (that show the statistical results with graphics).)
