tcp/ip协议建立连接三次握手的相关内容

TCP建立连接的三次握手

首先了解下TCP协议所在网络分层体系的位置以TCP/IP参考模型为例，可以看到TCP是作用在传输层的TCP的特点（1）TCP提供的是面向连接、可靠的数据流服务，数据传输完毕会释放连接（2）TCP提供的是端到端的通信，不支持多播和广播（3）通过超时重传、滑动窗口等机制保证字节流数据传输的稳定性和正确性...

为什么TCP建立连接需要经过三次握手，释放连接需要经过四次握手？

tcp建立连接为什么需要三次握手

这是一个看似很“简单”的问题，但貌似并没有一个官方统一的答案。搜索了相关的资料，列举出一些答案。以下部分转载自：tcp建立连接为什么需要三次握手在《计算机网络》一书中其中有提到，三次握手的目的是“为了防止已经失效的连接请求报文段突然又传到服务端，因而产生错误”，这种情况是：一端(client)A...
