RFC 6937: Proportional Rate Reduction for TCP

This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 9937.

Current version: RFC 9937 — Proportional Rate Reduction (PRR)

In plain English — editorial summary, not part of the RFC

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.
