Three Way Handshake

Three Way Handshake

An example of a TCP-Handshake (Three-Way-Handshake) written in Python.

TCP uses a three-way handshake to establish a reliable connection. The connection is full duplex, and both sides synchronize (SYN) and acknowledge (ACK) each other. The exchange of these four flags is performed in three steps—SYN, SYN-ACK, and ACK.
