43 .Cd options ALTQ_FAIRQ
47 framework provides several disciplines for queuing outgoing network packets.
48 This is done by modifications to the interface packet queues.
53 The user interface for
57 utility, so please refer to the
61 manpages for a complete description of the
63 capabilities and how to use it.
65 The following options in the kernel configuration file are related to
69 .Bl -tag -width ".Dv ALTQ_DEBUG" -compact
75 .Dq "Class Based Queuing"
79 .Dq "Random Early Detection"
83 .Dq "Random Early Drop"
87 .Dq "Hierarchical Packet Scheduler"
90 Build the traffic conditioner.
91 This option is meaningless at the moment as the conditioner is not used by
92 any of the available disciplines or consumers.
95 .Dq "Priority Queuing"
102 Required if the TSC is unusable.
104 Enable additional debugging facilities.
109 cannot be loaded as kernel modules.
110 In order to use a certain discipline you have to build it into a custom
114 interface, that is required for the configuration process of
