Abstract:
1. A system for hierarchically storing packetized data and transferring the packetized data, the apparatus comprising: an input configured to receive packets of data; an output coupled to a memory and configured to transfer packets of data from the memory; and control means coupled to the input and to the output for storing packets of data received by the input in queues associated with a hierarchy where each level of the hierarchy includes at least one group of queue group components, and where at least one of the queue group components in each level other than a lowest level of the hierarchy includes a group of queue group components associated with a logically-lower level of the hierarchy, each queue group component being associated with at least one of a logically-lower queue and a logically-lower queue group, the control means also for transferring stored packets of data to the output, wherein the control means is also for determining effective lengths of the queue group components.
