A method and apparatus for selecting a queue for service across a shared link. The method includes determining a priority for each queue ( 202 ) within a plurality of ingresses ( 102 ), wherein the priority is instantaneous for a given timeslot for data transfer, selecting a queue having a first priority for each group of queues within each ingress ( 104 ) having packets destined for a particular egress ( 104 ), selecting a queue having a second priority for each subset of queues having first priorities and having packets destined for the particular egress ( 104 ), and selecting the queue having the second priority for service across the shared link in the given timeslot.
