The IESG has approved the following document: - 'Convergence of Congestion Control from Retained State' (draft-ietf-tsvwg-careful-resume-23.txt) as Proposed Standard
This document is the product of the Transport and Services 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-tsvwg-careful-resume/ Technical Summary This document specifies a cautious method for IETF transports that enables fast startup of congestion control for a wide range of connections, known as "Careful Resume". It reuses a set of computed congestion control parameters that are based on previously observed path characteristics between the same pair of transport endpoints. These parameters are saved, allowing them to be later used to modify the congestion control behaviour of a subsequent connection. It describes assumptions and defines requirements for how a sender utilizes these parameters to provide opportunities for a connection to more rapidly get up to speed and rapidly utilise available capacity. It discusses how use of this method impacts the capacity at a shared network bottleneck and the safe response that is needed after any indication that the new rate is inappropriate. Working Group Summary A previous version of this document was originally submitted to the QUIC working group; the current, more general version was adopted by TSVWG. Document Quality There are four known implementations. As this is a sender-side mechanism, interoperability is not required per se, though they have interoperated with each other. Personnel The Document Shepherd for this document is Marten Seemann. The Responsible Area Director is Mike Bishop. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
