A network switch including a port for the reception and transmission of data packets, and a receive buffer store connected to the port, detecting a predetermined state of fullness of the buffer store, initiating in response to the state of fullness the production of control frames for signaling to a source of packets to pause the sending of packets to the switch, counting said frames to obtain a measure of congestion of the switch, and responsive to a rate of change of measure to enable the discarding of packets received by the buffer when rate is higher than a first predetermined value and to disable the discarding of packets when the rate of change of the measure is below a second predetermined value. |
