Received changes through RFC Editor sync (created alias RFC 8312, changed abstract to 'CUBIC is an extension to the current TCP standards.  It differs from the current TCP standards only in the congestion control algorithm on the sender side.  In particular, it uses a cubic function instead of a linear window increase function of the current TCP standards to improve scalability and stability under fast and long-distance networks.  CUBIC and its predecessor algorithm have been adopted as defaults by Linux and have been used for many years.  This document provides a specification of CUBIC to enable third-party implementations and to solicit community feedback through experimentation on the performance of CUBIC.', changed pages to 18, changed standardization level to Informational, changed state to RFC, added RFC published event at 2018-02-07, changed IESG state to RFC Published)
