+.SH 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.
+
+.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. See
+.BR tc-red (8)
+for a description.
