实验共有两个程序实验报告client和server.doc

实验报告 实验名称 Windows Socket 编程 课程名称 计算机网络 一、 实验目的 目的： （1）掌握网络应用程序的开发方法； （2）掌握Client/ Server 结构软件的设计与开发方法； （3）掌握Socket 机制的工作原理。 要求： （1）完成客户端与服务器之间信息的互传； （2）模拟的四种停止等待协议情况； （3）实现多客户端间信息交互（选作）。 二、 实验环境 Windows 操作系统，VC 6 开发环境 三、实验内容与结果 （1）实验程序 实验共有两个程序，client和server，分别代表客户端和服务器并实现相应功能。 （2）实现功能 本实验一共需实现5个功能：服务器和客户端的双向通信和四种停止等待协议的模拟，四种停止等待协议的示意图如下 （3）重要的算法 本实验采用了sleep函数模拟四种停止等待协议发生时的时间关系。 （4）实验结果 1．服务器与客户端的双向通信 Client Server server.exe [simplex-talk server] server is ready in listening ... client.exe localhost [simplex-talk server] received a connection from 127.0.0.1 : [simplex-talk client] connection to localhost is ready [simplex-talk client] please input your message (empty input to halt): dfghgj [simplex-talk client] send 7 chars to server [simplex-talk server] received 7 chars dfghgj dfghgd [simplex-talk server] send 7 chars to client [simplex-talk client] received 7 chars dfghgd [simplex-talk client] empty message is send to server [simplex-talk client] connection is terminated [simplex-talk server] empty message is received [simplex-talk server] connection from 127.0.0.1 is terminated 2．客户端消息到达服务器并返回ACK! Client Server server.exe [simplex-talk server] server is ready in listening ... client.exe localhost [simplex-talk server] received a connection from 127.0.0.1 : [simplex-talk client] connection to localhost is ready [simplex-talk client] please input your message (empty input to halt): dfghgj [simplex-talk client] send 7 chars to server [simplex-talk server] received 7 chars Dfghgj ACK! [simplex-talk server] send 5 chars to client [simplex-talk client] received 5 chars ACK! [simplex-talk client] empty message is send to server [simplex-talk client] connection is terminated [simplex-talk server] empty message is received [simplex-talk server] connection from 127.0.0.1 is terminated 3.客户端消息未到达服务器 Client Server server.exe [simplex-talk server] server is ready in listening ... client.exe localhost [simplex-talk server] received a connection from 127.
