Описание (Description)
CHOKe (CHOose and Keep for responsive flows, CHOose and Kill for
unresponsive flows) is a classless qdisc designed to both
identify and penalize flows that monopolize the queue. CHOKe is a
variation of RED, and the configuration is similar to RED.
Алгоритм (Algorithm)
Once the queue hits a certain average length, a random packet is
drawn from the queue. If both the to-be-queued and the drawn
packet belong to the same flow, both packets are dropped.
Otherwise, if the queue length is still below the maximum length,
the new packet has a configurable chance of being marked (which
may mean dropped). If the queue length exceeds max, the new
packet will always be marked (or dropped). If the queue length
exceeds limit, the new packet is always dropped.
The marking probability computation is the same as used by the
RED qdisc.
Параметры (Parameters)
The parameters are the same as for RED, except that RED uses
bytes whereas choke counts packets. See tc-red(8) for a
description.
