ALTQ(4)                      Device Drivers Manual                     ALTQ(4)

NAME
     altq - alternate queuing framework

DESCRIPTION
     The 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.

HISTORY
     The 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.

CAVEATS
     Please note that you must compile pf(4) in the kernel, using the PF
     module(7) alongside altq built in the kernel will not work.
