DESCRIPTION
The
altq 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.
