DESCRIPTION
Thealtq
framework 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
.
