Abstract

The authors present a high-performance self-routing packet switch architecture, called Sunshine, that can support a wide range of services having diverse performance objectives and traffic characteristics. Sunshine is based on Batcher-banyan networks and achieves high performance by utilizing both internal and output queuing techniques within a single architecture. This queuing strategy results in an extremely robust and efficient architecture suitable for a wide range of services. An enhanced architecture allowing the bandwidth from an arbitrary set of transmission links to be aggregated into trunk groups to create high bandwidth pipes is also presented. Trunk groups appear as a single logical port on the switch and can be used to increase the efficiency of the switch in an extremely bursty environment or to increase the access bandwidth for selected high-bandwidth terminations. Simulation results are presented
