CHOKe is a variation of RED, and the configuration is similar to RED. + +.SH 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 +.BR max , +the new packet will always be marked (or dropped). +If the queue length exceeds +.BR limit , +the new packet is always dropped. + +The marking probability computation is the same as used by the RED qdisc. + +.SH PARAMETERS +The parameters are the same as for RED, except that RED uses bytes whereas choke +counts packets.
