ABSTRACT:
A packet scheduling scheme schedules packets from a plurality of queues onto outgoing link. The scheme associates a weight and a virtual start time with each of the queues. Queues are selected, in order of the virtual start time, until a non-empty queue is selected. One or more packets are sent from the selected queue and then the virtual start time is updated, based on the length of the transmitted packet and the weight associated with the selected queue.
