TCP实现原理和为什么需要三次握手？两次握手不可以？四次握手不可以？读者可以带着疑问，看一遍富贵论坛www.fgba.net的详细讲解ok，首先解释原因之前还是要先复习一下TCP的基本知识和三次握手协议：1、什么是TCP协议？TCP：Transmission Control Protocol翻译过来...

深入浅出TCP协议的三次握手过程

TCP是主机对主机层的传输控制协议，提供可靠的连接服务，采用三次握手确认建立一个连接: 每一次TCP连接都需要三个阶段：连接建立、数据传送和连接释放。“三次握手”就发生在连接建立阶段。 1.三次握手（three times handshake）所谓的“三次握手”即对每次发送的数据量跟踪进行协商使数...
