Windows-Sockets

利用VC++6.0来实现一个类似QQ的聊天程序。本程序只实现添加好友，文字聊天，文件传输和语音聊天4大功能。(VC 6.0 to achieve a similar QQ chat program. This procedure will only add to achieve good friend, text chat, file transfer, and voice chat four major functions.)

使用Winsocket API实现的网络通信功能，分客户端和服务器端。(Winsocket API to achieve the use of the network communication function, sub-client and server.)

关于WSAEventselect模型的使用，这个模型和WSAAsyncselect很相像，但是使用方法还是要注意(About WSAEventselect model used is very similar to the model and WSAAsyncselect, but still have to pay attention to use)

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.)

黑客编程精粹，可以学到很多使用的东西啊，里面包含好几个文件(Hacker programming the essence of things you can learn a lot using the ah, which contains several files)

TCP和UDP socket编程，向固定服务器发送学号姓名信息，用udp从服务器获得一个随机字符串(TCP and UDP socket programming, Student ID Name information sent to the fixed server udp from server to obtain a random string)

获取远程机器的MAc地址，运行环境VC＋＋ (get MAC of remote machine)

Resource name HTTP and multi-threaded download

ns2网络仿真的实例以及对应测试分析代码，含有时延，抖动，丢包率等(ns2 network simulation examples and counterparts test analysis code, containing latency, jitter, packet loss rate etc.)

说明：  Socket是建立网络连接时使用的。在连接成功时，应用程序两端都会产生一个Socket实例，操作这个实例，完成所需的会话。(Socket is used when a network connection. The connection is successful, the application will have a Socket instance ends, the operation of this example, the completion of the required sessions.)
