       CHOKe (CHOose and Keep for responsive flows, CHOose and Kill for  unre-
       sponsive  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 the same as RED.

       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  config-
       urable  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

       The parameters are the same as for RED, see tc-red(8)  for  a  descrip-
