            "content": "CHOKe (CHOose and Keep for responsive flows, CHOose and Kill for  unresponsive  flows)  is  a\nclassless qdisc designed to both identify and penalize flows that monopolize the queue. CHOKe\nis a variation of RED, and the configuration is similar to RED.\n\n",

        },
        "ALGORITHM": {
            "content": "Once  the  queue  hits  a certain average length, a random packet is drawn from the queue. If\nboth the to-be-queued and the drawn packet belong to the same flow, both packets are dropped.\nOtherwise, if the queue length is still below the maximum length, the new packet has  a  con‐\nfigurable  chance of being marked (which may mean dropped).  If the queue length exceeds max,\nthe new packet will always be marked (or dropped).  If the queue length  exceeds  limit,  the\nnew packet is always dropped.\n\nThe marking probability computation is the same as used by the RED qdisc.\n\n",

        "PARAMETERS": {
            "content": "The parameters are the same as for RED, except that RED uses bytes whereas choke counts pack‐\nets. See tc-red(8) for a description.\n\n",
