Understanding TCP Connection Termination: Four-Way Handshake, Half‑Close, Shutdown, and TIME_WAIT

This article explains how TCP connections are gracefully closed using the four‑way handshake, describes half‑close and half‑open states, compares the close and shutdown system calls, details the TIME_WAIT state and its impact, and offers practical techniques to reduce or avoid TIME_WAIT accumulation.

Why TCP Can Close Connections in 2, 3, or 4 Handshakes – Hidden Mechanics Explained

This article explores TCP’s connection termination process, detailing the classic four‑way handshake, scenarios that reduce it to three or two handshakes, the concept of self‑connections, simultaneous opens, and practical implications for developers, including code examples and troubleshooting tips.
