The IESG has approved the following document: - 'Proportional Rate Reduction' (draft-ietf-tcpm-prr-rfc6937bis-21.txt) as Proposed Standard
This document is the product of the TCP Maintenance and Minor Extensions Working Group. The IESG contact persons are Gorry Fairhurst and Mike Bishop. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-tcpm-prr-rfc6937bis/ Technical Summary This document is a product of the TCPM working group. 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 loss recovery. This will be as close as possible to the slow start threshold (ssthresh), as determined by the congestion control algorithm. The WG notes that this has received feedback from the implementors of Linux and FreeBSD among others. There was a broad consensus in the WG on the document including from major OS implementers such as Linux, FreeBSD and Windows as the previous version of the algorithm has already been used by these OSes as the default. 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. Personnel The Document Shepherd for this document is Yoshifumi Nishida. The Responsible Area Director is Gorry Fairhurst. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
