[FAIRQUEUEINGCONTROLLEDDELAY] SECTION OPTIONS

The [FairQueueingControlledDelay] section manages the queueing discipline (qdisc) of fair queuing controlled delay (FQ-CoDel).

Parent= Configures the parent Queueing Discipline (qdisc). Takes one of "root", "clsact", "ingress" or a class identifier. The class identifier is specified as the major and minor numbers in hexadecimal in the range 0x1–Oxffff separated with a colon ("major:minor"). Defaults to "root".

Handle= Configures the major number of unique identifier of the qdisc, known as the handle. Takes a hexadecimal number in the range 0x1–0xffff. Defaults to unset.

PacketLimit= Specifies the hard limit on the real queue size. When this limit is reached, incoming packets are dropped. Defaults to unset and kernel's default is used.

MemoryLimitBytes= Specifies the limit on the total number of bytes that can be queued in this FQ-CoDel instance. When suffixed with K, M, or G, the specified size is parsed as Kilobytes, Megabytes, or Gigabytes, respectively, to the base of 1024. Defaults to unset and kernel's default is used.

Flows= Specifies the number of flows into which the incoming packets are classified. Defaults to unset and kernel's default is used.

TargetSec= Takes a timespan. Specifies the acceptable minimum standing/persistent queue delay. Defaults to unset and kernel's default is used.

IntervalSec= Takes a timespan. This is used to ensure that the measured minimum delay does not become too stale. Defaults to unset and kernel's default is used.

QuantumBytes= Specifies the number of bytes used as the "deficit" in the fair queuing algorithm timespan. When suffixed with K, M, or G, the specified size is parsed as Kilobytes, Megabytes, or Gigabytes, respectively, to the base of 1024. Defaults to unset and kernel's default is used.

ECN= Takes a boolean. This can be used to mark packets instead of dropping them. Defaults to unset and kernel's default is used.

CEThresholdSec= Takes a timespan. This sets a threshold above which all packets are marked with ECN Congestion Experienced (CE). Defaults to unset and kernel's default is used.
