receiving data packets from senders;

tracking data packet transmission rates of the senders;

implementing an accented congestion management protocol that expects each of the senders to decrease its respective data transmission rate if congestion occurs;

detecting congestion or potential congestion;

during the congestion or potential congestion, determining that one or more of the senders deviate from the accepted congestion management protocol by comparing, for each sender, a present data packet transmission rate to a prior tracked data transmission rate for the sender to determine whether the sender maintained or increased its rate of data packet transmission in violation of the accented congestion management protocol;

rank ordering the one or more of the senders according to egregiousness of their deviation from the accented congestion management protocol to generate a rank ordered list of one or more worst offenders;

identifying which of the received data packets are from the one or more worst offenders of the rank ordered list;

marking the identified data packets for dropping;

queuing in a queue, according to received order, the received data packets, including the identified data packets marked for dropping; and

transmitting the received data packets from a head of the queue except for at least some of those data packets marked for dropping which were received from a most egregious one of the one or more worst offenders according to the rank ordered list wherein a decision for not transmitting occurs based on the marking as each of the marked, identified data packets reaches the head of the queue.
