多线程通信 程序说明 Ⅰ、设计项目： 简单的聊天程序 Ⅱ、设计人： 刘亚焱 Ⅲ、设计时间： 2003.5.6 Ⅳ、设计步骤： 1）需求分析： 用java实现底层网络通信，我用的是 TCP/IP协议里的套接字（Socket）编程接口来实现网络通讯。 2）设计部分： socket是一种流式通信机制，是一种基于连接的通信，即，在通信之前通信双方确认身份并建立一条 专用的虚拟连接通道，然后他们通过这条通道传送数据信息进行通信，当通信结束时再将原来所建的连 接拆除。-multithreaded communications description of the procedures, design projects : a simple chat program II, designer : Liu Yan III, the design time : 2003.5.6 IV, the design steps : 1) Demand Analysis : java achieve underlying network communication, I use the TCP/The IP socket (Socket) programming interfaces to network communications. 2) Design : socket is a streaming communication mechanism is based on a link of communication, namely, the communication before the two sides identified telecommunications and the establishment of a dedicated virtual link, and then they pass this information channel for transmission of data communications, when the communication ended when it originally construction of the link removed.
