ABSTRACT:
A novel packet switch architecture is disclosed. The packet switch utilizes internal queuing (i.e. recirculation loops) and output queuing (i.e. multiple paths to each destination) to provide a packet switch which offers superior performance in comparison to a packet switch which utilizes either of these queuing strategies alone. The combination of recirculation and output queues have complimentary effects. The output queuing reduces the number of recirculation loops needed and recirculation reduces the bandwidth requirements for an output buffered switch.
