Apparatus and method for queuing flow management between input, intermediate and output queues

摘要

An apparatus is described that includes a plurality of queuing paths. Each of the queuing paths further comprises an input queue, an intermediate queue and an output queue. The input queue has an output coupled to an input of the intermediate queue and the input of the output queue. The intermediate queue has an output coupled to the input of the output queue. The intermediate queue receives data units from the input queue if a state of the input queue has reached a threshold. The output queue receives data units from the intermediate queue if the intermediate queue has data units. The output queue receives data units from the input queue if the intermediate queue does not have data units.
