网络内容过滤系统，使用中间层驱动过滤IP，LSP过滤URL和关键字！(Text content, url, URL, ip filter voice prompts can be issued according to the text, and fast alarm 3 software set certain security measures to protect and prevent tampering and unauthorized access 4. Through illegal information characteristics to upgrade the feature library.)

说明：  vb做的局域网监控系统，同学的毕业设计，研究winsock很有用(vb to do the LAN monitoring system, students graduating from design, research useful winsock)

raw socket编程，探测网络包。 vc++, win2000测试通过。(raw socket programming, detect network packets. vc++, win2000 test passed.)

Network transmission

：本系统属于小型的局域网监控系统，可以对某一台计算机进行屏幕监控，本系统主要实现以下功能：  系统采用人机交互的方式，界面美观友好。  屏幕信息需要时时显示，网络延时不能大于1秒。  服务器端可以随时运行，只要客户端运行，就能够显示屏幕信息。  系统运行时占用内存不能大于10MB，以免影响系统性能。  客户端运行时需要隐藏显示窗口，起其感觉不到在运行(network monitoring system that can carry out the screen of a computer monitor, the system achieve the following features:  system is the way human-computer interaction, interface, beautiful and friendly.  need to constantly display screen information, the network delay is not greater than 1 second.  server can be run at any time as long as the client runs, will be able to display information.  run-time memory for the system can not be larger than 10MB, so as not to affect system performance.  need to hide the client run-time display window, from its feel in the run.)

实习UDP网络通信,通过windows下UDP(come true UDP socket communition.)

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).)

windows网络编程的工程文件和源代码，主要讲iocp模型的用法，实现一个管理系统。(windows network programming project file and source code, mainly about the use of iocp model, implement a management system.)

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)

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.)
