Abstract
A packet scheduling scheme which is capable of improving the fairness characteristic in a short time scale by suppressing the burstiness of traffic compared with the conventional weight fair queueing algorithm such as DRR. Packets are held in a plurality of packet queues by inputting arrived packets into the packet queues. Then, an output packet queue is sequentially selected from the packet queues, according to a prescribed criterion based on an amount of packets currently transmittable by each packet queue, such that the output packet queue is selected to be different from a previously selected output packet queue when there are more than one packet queues that satisfy the prescribed criterion. Then, a top packet is outputted from the sequentially selected output packet queue.
