Input queueing is becoming increasingly used for high-bandwidth switches and routers. In previous work, it was proved that it is possible to achieve 100% throughput for input-queued switches using a combination of virtual output queueing and a scheduling algorithm called LQF. However, this is only a theoretical result: LQF is too complex to implement in hardware. In this paper we introduce a new algorithm called Longest Port First (LPF), which is designed to overcome the complexity problems of… CONTINUE READING
