Abstract
Buffered crossbar switches are a special type of crossbar switches. In such a switch, besides normal input queues and output queues, a small buffer is associated with each crosspoint. Due to the intro-duction of crosspoint buffers, output and input contention is elimi-nated, and the scheduling process for buffered crossbar switches is greatly simplified. Moreover, crosspoint buffers enable the switch to work in an asynchronous mode and easily schedule and trans-mit variable length packets. Compared with fixed length packet scheduling or cell scheduling, variable length packet scheduling, or packet scheduling for short, has some unique advantages: higher throughput, shorter packet latency and lower hardware cost. In this paper, we present a fast and practical scheduling scheme for buffered crossbar switches called Localized Asynchronous Packet Scheduling (LAPS). With LAPS, an input port or output port makes
