Rate optimal scheduling schemes for asynchronous input-queued packet switches

Abstract : The performance of input-queued packet switches critically depends on the scheduling scheme that connects the input ports to the output ports. We show that, when packets are switched asynchronously, simple scheduling schemes where contention is solved locally at each input or output can achieve rate optimality, without any speed-up of the internal transmission rate.
