Abstract
A system is described where delay and bandwidth guarantees are implemented with a crossbar switch. A rate controller is provided as a front-end to a crossbar switch with an arbiter running a work-conserving arbitration algorithm. The system provides bandwidth and delay guarantees to all properly behaving flows independently of improperly behaving flows.
