Abstract
A network device which includes flow control, being responsive to a control frame prescribing a pause in the forwarding of packet from a port, sorts received packets intended for forwarding from that port into a first queue, e.g. critical latency traffic and at least one other queue. A count of the number of packets in the first queue is determined at the onset of a pause and at least that number of packets are discarded from the first queue if the pause time exceeds a programmable reference.
