1.2.3.相比于TCP通信，UDP不存在客户端和服务器端的实际连接，因此不需要为连接（channelPipeline）设置handler,对于服务端，只需设置启动辅助类的handler即可。

应用背景基于Qt的局域网聊天系统，实现了局域网聊天，文件传输，更改字体，保存聊天记录等功能，对于研究Qt，研究局域网通信具有较强学习价值。关键技术udpSocket = new QUdpSocket(this); port = 45454; udpSocket->bind(port, QUdpSocket::ShareAddress | QUdpSocket::ReuseAddressHint); connect(udpSocket, SIGNAL(readyRead()), this, SLOT(processPendingDatagrams())); sendMessage(NewParticipant); server = new TcpServer(this); connect(server, SIGNAL(sendFileName(QString)), this, SLOT(getFileName(QString))); connect(ui->messageTextEdit, SIGNAL(currentCharFormatChanged(QTextCharFormat)), this, SLOT(currentFormatChanged(const QTextCharFormat)));

SimCDIR，模拟路由CDIR的过程，其中附有操作文档，基于VS2005 C#开发。-SimCDIR, analog routing CDIR process, including an operation of the document, based on the VS2005 C# Development.

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.)
