Note that hystart++ requires the TCP stack be able to call to the congestion controller with both the newround function as well as the rttsample function. Currently the only TCP stacks that provide this feedback to the congestion controller is rack.

This was the default congestion control algorithm in FreeBSD before version FreeBSD 14.0, after which cc_cubic(4) replaced it.

The module was first released in 2007 by James Healy and Lawrence Stewart whilst working on the NewTCP research project at Swinburne University of Technology's Centre for Advanced Internet Architectures, Melbourne, Australia, which was made possible in part by a grant from the Cisco University Research Program Fund at Community Foundation Silicon Valley.
