altq
system is a framework which provides several
disciplines for queuing outgoing network packets. While traffic shaping is
perhaps the most prominent example, altq
provides also
other measures related to QoS. The framework has been integrated to the
pf(4) packet filter since
NetBSD 4.0.
At the implementation level altq
modifies
the interface packet queues. Therefore the driver modifications described in
altq(9) are required in order to
use a certain network card with altq
.

altq
system first appeared in March 1997 and found
its home in the KAME project
(http://www.kame.net). It was
imported into NetBSD 1.6.
altq
built in the kernel will not work.
