altq(4) to match altq(9). This makes preserving the history section as the author of ALTQ easier in the history section, rather than calling it a framework in the description & a system in the history. Add a history section to altq(4) and extend the history section in altq(9) Approved by: bcr (mentor) MFC after: 5 days Differential Revision: https://reviews.freebsd.org/D14774

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
system is a framework which provides several disciplines for queuing outgoing
|
|
network packets.
|
|
This is done by modifications to the interface packet queues.
|
|
See
|
|
.Xr altq 9
|
|
for details.
|
|
.Pp
|
|
The user interface for
|
|
.Nm
|
|
is implemented by the
|
|
.Xr pfctl 8
|
|
utility, so please refer to the
|
|
.Xr pfctl 8
|
|
and the
|
|
.Xr pf.conf 5
|
|
man pages for a complete description of the
|
|
.Nm
|
|
capabilities and how to use it.
|
|
.Ss Kernel Options
|
|
The following options in the kernel configuration file are related to
|
|
.Nm
|
|
operation:
|
|
.Pp
|
|
.Bl -tag -width ".Dv ALTQ_DEBUG" -compact
|
|
.It Dv ALTQ
|
|
Enable
|
|
.Nm .
|
|
.It Dv ALTQ_CBQ
|
|
Build the
|
|
.Dq "Class Based Queuing"
|
|
discipline.
|
|
.It Dv ALTQ_CODEL
|
|
Build the
|
|
.Dq "Controlled Delay"
|
|
discipline.
|
|
.It Dv ALTQ_RED
|
|
Build the
|
|
.Dq "Random Early Detection"
|
|
extension.
|
|
.It Dv ALTQ_RIO
|
|
Build
|
|
.Dq "Random Early Drop"
|
|
for input and output.
|
|
.It Dv ALTQ_HFSC
|
|
Build the
|
|
.Dq "Hierarchical Packet Scheduler"
|
|
discipline.
|
|
.It Dv ALTQ_CDNR
|
|
Build the traffic conditioner.
|
|
This option is meaningless at the moment as the conditioner is not used by
|
|
any of the available disciplines or consumers.
|
|
.It Dv ALTQ_PRIQ
|
|
Build the
|
|
.Dq "Priority Queuing"
|
|
discipline.
|
|
.It Dv ALTQ_FAIRQ
|
|
Build the
|
|
.Dq "Fair Queuing"
|
|
discipline.
|
|
.It Dv ALTQ_NOPCC
|
|
Required if the TSC is unusable.
|
|
.It Dv ALTQ_DEBUG
|
|
Enable additional debugging facilities.
|
|
.El
|
|
.Pp
|
|
Note that
|
|
.Nm Ns -disciplines
|
|
cannot be loaded as kernel modules.
|
|
In order to use a certain discipline you have to build it into a custom
|
|
kernel.
|
|
The
|
|
.Xr pf 4
|
|
interface, that is required for the configuration process of
|
|
.Nm
|
|
can be loaded as a module.
|
|
.Sh SUPPORTED DEVICES
|
|
The driver modifications described in
|
|
.Xr altq 9
|
|
are required to use a certain network card with
|
|
.Nm .
|
|
They have been applied to the following hardware drivers:

|
|

|
|
.Pp
|
|
The
|
|
.Xr ndis 4
|
|
framework also has support for
|
|
.Nm
|
|
and thus all encapsulated drivers.
|
|
.Pp
|
|
The
|
|
.Xr tun 4
|
|
and
|
|
.Xr ng_iface 4
|
|
pseudo drivers also do support
|
|
.Nm .

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
system first appeared in March 1997 and found home in the KAME project
|
|
(http://www.kame.net).
|
|
It was imported to
|
|
.Fx
|
|
in 5.3 .
