I ported altq 2.0 to OpenBSD..This provides traffic shaping and quality of
service features for OpenBSD
ALTQ 2.0 is covered mostly by BSD-like licenses that allow for a wide range
of use and redistribution of the software. The only exceptions are
cbq-tools/rsvp_cbq.c, which is built into cbq-tools/cbqd, and is not
necessary for most of the functionality of alt 2.0 (CBQ discipline can be
manipulated from altqd starting with release 2.0)
You can find my port at ftp://dqc.org/pub/altq/ along with the original
source and Kenjiro Cho's Usenix paper on ALTQ in PDF and PostScript format.
I know a number of folks are interested in traffic shaping on OpenBSD, and to
a lesser extent some may be curious about QoS, so please grab this package
and try it out. This package makes major changes to the midway ATM adapter
code, which bring OpenBSD into sync with FreeBSD and NetBSD in this respect.
Altq requires a few usually minor changes to your NIC driver before
it can perform its magic. Several patches for existing OpenBSD drivers are
already included, of course. I attempted to make the documentation
consistent, so from README:
