tcp/ip协议报文格式-阿里云

TCP/IP协议中分包与重组原理介绍、分片偏移量的计算方法、IPv4报文格式

一、什么是IP分片IP分片是网络上传输IP报文的一种技术手段。IP协议在传输数据包时，将数据报文分为若千分片进行传输，并在目标系统中进行重组,这一过程称为分片(fragmentation).二，为什么要进行IP分片（1500) 6+6+2+4以太网技术支持帧大小最大为1518字节。通常以太网接口默...

结合Wireshark捕获分组深入理解TCP/IP协议栈之TCP协议(TCP报文格式+三次握手实例)

摘要：本文简单介绍了TCP面向连接理论知识，详细讲述了TCP报文各个字段含义，并从Wireshark俘获分组中选取TCP连接建立相关报文段进行分析。一、概述 TCP是面向连接的可靠传输协议，两个进程互发数据...
