TCP and Stream Control Transmission Protocol RTO Restart

Overview

RFC 7765, “TCP and Stream Control Transmission Protocol RTO Restart”, is an Experimental document published in February 2016 by P. Hurtig, A. Brunstrom, A. Petlund, M. Welzl. The canonical text is published by the RFC Editor.

Abstract

This document describes a modified sender-side algorithm for managing the TCP and Stream Control Transmission Protocol (SCTP) retransmission timers that provides faster loss recovery when there is a small amount of outstanding data for a connection. The modification, RTO Restart (RTOR), allows the transport to restart its retransmission timer using a smaller timeout duration, so that the effective retransmission timeout (RTO) becomes more aggressive in situations where fast retransmit cannot be used. This enables faster loss detection and recovery for connections that are short lived or application limited.
