HyStart++: Modified Slow Start for TCP
RFC 9406

Received changes through RFC Editor sync (created alias RFC 9406, changed abstract to 'This document describes HyStart++, a simple modification to the slow start phase of congestion control algorithms.  Slow start can overshoot the ideal send rate in many cases, causing high packet loss and poor performance.  HyStart++ uses increase in round-trip delay as a heuristic to find an exit point before possible overshoot.  It also adds a mitigation to prevent jitter from causing premature slow start exit.', changed pages to 9, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2023-05-15, changed IESG state to RFC Published)
