Embodiment Construction
[0050] A quick way to solve the out-of-sequence problem with a load-balanced switch with a first-level buffer is to add a reordering and output buffer after the second-level switch fabric. However, the distribution of packets in the first-level crossbar switch fabric is based on the packet arrival time, so there is no guarantee that the reordering and output buffers are large enough to prevent packet loss. Therefore, the distribution of packets in the first-level crossbar fabric is based on their flow rather than arrival time. Therefore, we must add a traffic splitter and a load balancing buffer in front of the first level crossbar switch fabric.
[0051] The present invention provides a load balancing switching device with multi-level buffers. By adding a load buffer before the first-level crossbar switch fabric, and adding a reordering and output buffer after the second-level crossbar switch fabric. The distribution of packets in the first-level crossbar fabric is based on...
