Reducing the TIME-WAIT State Using TCP Timestamps

Metadata

Publisher: IETF
Doc Type: Best Practice
Pages: 10
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.
