.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
framework provides several disciplines for queuing outgoing network packets.
|
|
|
|
|
While traffic shaping is perhaps the most prominent example,
|
|
|
|
|
.Nm
|
|
|
|
|
provides also other measures related to QoS.
|
|
|
|
|
The framework has been integrated to the
|
|
|
|
|
.Xr pf 4
|
|
|
|
|
packet filter since
|
|
|
|
|
.Nx 4.0 .
|
|
|
|
|
.Pp
|
|
|
|
|
At the implementation level
|
|
|
|
|
.Nm
|
|
|
|
|
modifies the interface packet queues.
|
|
|
|
|
Therefore the driver modifications described in

|
