实 验 报 告 实验名称 Windows Socket 编程 课程名称 计算机网络 实验目的 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 实验环境 Windows 操作系统，VC 开发环境 实验内容与结果 运行simplex-talk 例程，理解代码并观察现象 Client 端 Server 端 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): Hello！ [simplex-talk client] send 7 chars to server [simplex-talk server] received 7 chars Hello！ a [simplex-talk client] send 2 chars to server [simplex-talk server] received 2 chars a [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 从运行过程来看本程序实现了点到点的单向通信，即一端发一端收。 修改simplex-talk 程序，编制duplex-talk 程序，支持client 和server 的双向通信 Duplex-talk 程序运行结果（1） Client 端 Server 端 erdserver.exe [duplex-talk server] server is ready in listening ... erdclient.exe localhost [duplex-talk server] received a connection from 127.0.0.1 : [duplex-talk client] connection to localhost is ready [duplex-talk client] please input your message (empty input to halt) Hi [duplex-talk client] send 3 chars to server [duplex-talk server] received 3 chars Hi Got it [duplex-talk server] send 7 chars to client [duplex-talk client] received 7 chars Got it Bye [duplex-talk client] send 4 chars to server [duplex-talk server] received 4 chars Bye BYE [duplex-talk server] send 4 chars to client [duplex-talk client] received 4 chars BYE [duplex-talk client] empty message is send to server [duplex-talk client] connection is terminated [duplex-talk server] empty message is received [duplex-talk server] connection from 127.0.0.1 is terminated 这次我们实现了客户端和服务器之间的双向通信，具体过程是客户端先发起对话，然后服务器与客户端之间交替传递信息。 要实现上述功能，我们将客户端的发送模块加入到了服务器端，将服务器的接收模块加入到了客户端。 3.模拟client 和server 之间的stop-and-wait 的动作 客户
