Abstract:
1. A packet-buffering system in a communication device for transferring packets received over a communications network from an input port to an output port of the communication device, the system comprising: a first-level memory segmented into a plurality of first-level queues each having a first-buffer depth, the plurality of first-level queues receiving the packets from the input port of the communication device; and a second-level memory in communication with the first-level memory and the output port, the second-level memory being segmented into a plurality of second-level queues each having a second-buffer depth and being associated with the output port of the communication device, the plurality of second-level queues receiving packet data from at least one of the plurality of first-level queues and transferring the packet data to the output port, wherein a sum of the second-buffer depths exceeds a sum of the first-buffer depths.
