Abstract: Methods, apparatus and program products for controlling a flow of a pluralit y of packets in a computer network are disclosed. The computer network include s a device defining a queue. The methods, apparatus and program products inclu de determining a queue level for the queue and determining an offered rate of t he plurality of packets to the queue. They also include controlling a transmission fraction of the plurality of packets to or from the queue, base d on the queue level, the offered rate and a previous value of the transmissio n fraction so that the transmission fraction and the queue level are criticall y damped if the queue level is between at least a first queue level and a seco nd queue level. Several embodiments are disclosed in which various techniques a re used to determine the manner of the control.
