The IESG has approved the following document: - 'CUBIC for Fast Long-Distance Networks' (draft-ietf-tcpm-cubic-07.txt) as Informational RFC This document is the product of the TCP Maintenance and Minor Extensions Working Group. The IESG contact persons are Mirja Kühlewind and Spencer Dawkins. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-tcpm-cubic/ Technical Summary This document describes CUBIC which is a congestion control algorithm used in TCP. CUBIC modifies the standard congestion control mechanism in TCP in order to address low utilization issues for networks with large BDP. CUBIC is well deployed in the current Internet since it has been used as the default congestion control scheme in Linux. The objective of the draft is to document the mechanism of CUBIC in Linux code as an informational RFC. Working Group Summary The TCPM working group has discussed how to document CUBIC mechanism and reached the consensus to describe what is currently implemented as an informational RFC. While the WG spent two year to discuss the draft, no major controversial point has been raised during this process. Document Quality The draft has been reviewed and discussed by various participants in the WG including experts from Linux kernel development community which have been useful to adjust the description of detailed logics. Personnel The document shepherd is Yoshifumi Nishida <nishida@sfc.wide.ad.jp>. The responsible Area Director is Mirja Kuehlewind <ietf@kuehlewind.net>.
