Proportional Rate Reduction for TCP
RFC 6937, “Proportional Rate Reduction for TCP”, is an Experimental document published in May 2013 by M. Mathis, N. Dukkipati, Y. Cheng. It has been obsoleted by RFC 9937 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes an experimental Proportional Rate Reduction (PRR) algorithm as an alternative to the widely deployed Fast Recovery and Rate-Halving algorithms. These algorithms determine the amount of data sent by TCP during loss recovery. PRR minimizes excess window adjustments, and the actual window size at the end of recovery will be as close as possible to the ssthresh, as determined by the congestion control algorithm.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
