Ballot Text

Technical Summary

   This document updates the experimental Proportional Rate Reduction
   (PRR) algorithm, described RFC 6937, to standards track.  PRR
   provides logic to regulate the amount of data sent by TCP or other
   transport protocols during fast recovery.  PRR accurately regulates
   the actual flight size through recovery such that at the end of
   recovery it will be as close as possible to the slow start threshold
   (ssthresh), as determined by the congestion control algorithm.

Working Group Summary

This draft specifies a congestion control algorithm during recovery period which is the updated version of RFC6317 published 12 years ago.
The intention of the draft is to promote the specification to a proposed standard based on the experiences accumulated over the period.
Sections 3 and 4 provide the rationale for why this update is needed to the current RFC for PRR. The intended status of the document is Proposed Standard as there is a strong consensus in the WG. Publication will obsolete RFC6937 as the new specification for PRR and will move the specification to the Standards Track.
