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

This document is a product of the TCP Maintenance and Minor Extensions Working Group of the IETF.

This is now a Proposed Standard.
