The HFSC QoS kernel and a graphical user interface program have been implemented for Altq-2.0 (FreeBSD-3.3, 3.2 or 2.2.8.), NetBSD 1.2D, FreeBSD 2.2.6. The distribution includes software support for IETF intserv service models and RSVP signaling.

Altq-2.0 distribution Altq is a software package developed by Kenjiro Cho of Sony that supports alternate queueing for FreeBSD systems. H-FSC is now incorporated as one of the queueing discipline.
