The NewReno Modification to TCP's Fast Recovery Algorithm

Overview

RFC 3782, “The NewReno Modification to TCP's Fast Recovery Algorithm”, is a Proposed Standard document published in April 2004 by S. Floyd, T. Henderson, A. Gurtov. It obsoletes RFC 2582. It has been obsoleted by RFC 6582 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.

Abstract

The purpose of this document is to advance NewReno TCP's Fast Retransmit and Fast Recovery algorithms in RFC 2582 from Experimental to Standards Track status. The main change in this document relative to RFC 2582 is to specify the Careful variant of NewReno's Fast Retransmit and Fast Recovery algorithms. The base algorithm described in RFC 2582 did not attempt to avoid unnecessary multiple Fast Retransmits that can occur after a timeout. However, RFC 2582 also defined "Careful" and "Less Careful" variants that avoid these unnecessary Fast Retransmits, and recommended the Careful variant. This document specifies the previously-named "Careful" variant as the basic version of NewReno TCP. [STANDARDS-TRACK]

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
