Other TCP Connection Establishment Methods

Understand the various methods TCP uses to establish connections including the standard three-way handshake and simultaneous connection setups. Learn how TCP uses a finite state machine to manage states on both client and server sides, enabling reliable data exchange and connection management.

In the last lesson, we looked at the most common way that TCP connection establishment could occur. Now, let’s look at some other ways it can successfully occur.

A TCP Three-way Handshake FSM

TCP connection establishment can be described with a four-state Finite State Machine (FSM) as shown below. In this FSM, X/YX/Y ...
