  • 一篇文章贯穿ACE各种发送接收组件 1.2版

    TCP通信过程介绍

        首先介绍一下socket通信的基本过程:这里先如果有两个家伙在通信,一个是S。还有一个叫C

    (1)S打开port监听本地的port看看有没有人来连接;

    (2)与此同一时候C试图去连接远程的S。连接的地址就是S的地址加上S监听的port号;

    (3)S收到C的请求之后,建立连接,两方共同持有连接的通道。可互相发送/接收数据随意次。此时S和C无差别。

    (4)当中一方断开连接,或者由于网络原因中断连接,还有一方也会关闭;

    (5)此时通信过程结束;

    整个步骤例如以下图所看到的


    普通ACE通信类ACE_SOCK_*通信过程

    ACE_SOCK_Connector  ACE_SOCK_Stream  ACE_SOCK_Acceptor完毕上面的通信过程:

    Client:发送自己的签名给Server之后就准备接受Server发来的时间

    Server:在连接建立后打印对方发来的签名。之后回复自己的时间给对方
