Abstract
A method for scheduling a network resource comprises adding tokens to first and second accumulators at first and second fill rates, respectively. A number of tokens corresponding to a size of a packet is subtracted from the first accumulator and a highest priority is assigned to a queue with which the packet is associated, if a number of tokens in the first accumulator is greater than zero. The number of tokens is subtracted from the second accumulator, and a default priority assigned to the queue, if the number of tokens in the first accumulator is less than zero and a number of tokens in the second accumulator is greater than zero. The network resource is assigned for transmission of the packet from the queue using a schedule that is based on the priority assigned to the queue. The packet is transmitted using the assigned network resource.
