Design of an Expandable Crossbar Scheduler Based on iSLIP Algorithm

摘要

Crossbar switches are frequently used as the internal switching fabric of high-performance network switches and routers. However, an intelligent centralized scheduler is needed to configure the crossbar fairly and with high utilization. In this paper, we give the design of an expandable crossbar scheduler based on iSLIP algorithm, and then propose a simple to implement, non-block expanding scheme of the crossbar architecture.
