Reducing the TIME-WAIT State Using TCP Timestamps

Overview

RFC 6191, “Reducing the TIME-WAIT State Using TCP Timestamps”, is a Best Current Practice document published in April 2011 by F. Gont. The canonical text is published by the RFC Editor.

Abstract

This document describes an algorithm for processing incoming SYN segments that allows higher connection-establishment rates between any two TCP endpoints when a TCP Timestamps option is present in the incoming SYN segment. This document only modifies processing of SYN segments received for connections in the TIME-WAIT state; processing in all other states is unchanged. This memo documents an Internet Best Current Practice.
