1. A method for controlling a flow of a plurality of packets in a computer network including a queue, the method comprising the steps of(a) determining a queue level for the queue;

  • (b) determining an offered rate of the plurality of packets to the queue;

    (c) controlling a transmission fraction of the plurality of packets to the queue, based on the queue level and the offered rate, so that the transmission fraction and the queue level are damped if the queue level is between at least a first queue level and a second queue level, wherein the transmission fraction is controlled after each of a plurality of epochs and wherein the transmission fraction controlling step (c) further includes the step of;

    (c1) controlling the transmission fraction for an epoch of the plurality of epochs based on the queue level for a previous epoch, the offered rate for the previous epoch and the transmission fraction for the previous epoch such that the transmission fraction for the epoch and the queue level for the previous epoch would be damped.
