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.)

tcp/ip通信用VC++6.0开发的 基于三层结构(tcp/ip communication VC++ 6.0 developed based on the three-tier architecture)

VB开发的IP测试程序，这是在我工作中写的调试程序，在配置文件中只需要写上相应的IP，程序就会循环测试IP地址是否在线，不在线的话就会报警提醒(VB development of IP test program, which is written in my work debugger, just write in the configuration file on the corresponding IP, the program will loop test IP address is online, not online, then it will alarm to remind)

SOCKET通信，一个服务端，一个客户端的通信。(SOCKET communications, a server, a client communication.)

用socket实现客户端服务器上传下载传输文件(use socket download file)

说明：  ＰＩＮＧ程序源码有记录路由功能，希望对你们有帮助(PING record procedures source routing function, and I hope to help you)

黑客攻击与防范技术，我所保存的最全的网络安全资料。(Hacker attacks and prevention techniques, I have saved the most complete network security information.)

通信网络的架设问题 若要在n（≥10）个城市之间建设通信网络，只需要架设n-1条线路即可(With the Dijksra algorithm to network G from source points to the rest of the vertices of the shortest path)

用于将网络边关系转换成matlab可用的临近矩阵。(Used to convert the network edge into matlab available close relationship matrix.)
