Abstract:
1. A method in an integrated network switch, the method comprising: assigning a received data packet to a selected one of a plurality of priority queues for an output switch port; determining whether the selected one priority queue has at least a required number of tokens corresponding to a determined size of the received data packet, the selected one priority queue having an available number of tokens based on outputting data packets of respective determined sizes from the corresponding selected one priority queue relative to a prescribed token regeneration rate; selectively supplying the received data packet to the selected one priority queue based on the selected one priority queue having at least the required number of tokens; and outputting the received data packet from the selected one priority queue, relative to the plurality of priority queues, for transmission by the output switch port based on a prescribed weighted round robin scheduling between the priority queues.
