Abstract:
In a packet switched communication system including a traffic shaper and a relatively high data rate port that is time multiplexed to feed packet traffic to a plurality of relatively low data rate physical layers, said packet switched communication system comprising:a queuing mechanism, said queuing mechanism organizing packet traffic to said physical layers in respective queues in accordance with an oldest pending packet at head of queue order;a non-work conserving calendar queue mechanism coupled to said queuing mechanism, said non-work conserving calendar queue mechanism controlling the emission of packet traffic to said physical layers; anda scheduling mechanism coupled to said queuing mechanism and to said calendar queue mechanism, said scheduling mechanism scheduling packet traffic for emission to respective physical layers on said non-work conserving calendar queue mechanism at a rate substantially equal to or less than a data rate of said physical layers.
