Abstract :
An experimental 640-Gbit/s ATM switching system is described. The switching system is scalable and quasi-nonblocking. It uses hardware self-rearrangement in a three-stage network. Hardware implementation results for the switching system is presented. The switching system is fabricated using advanced 0.25 μm CMOS devices, high-density multi-chip-module (MCM) technologies, and optical wavelength division multiplexed (WDM) interconnection technologies. A scalable 80-Gbit/s switching module is fabricated combined with a newly developed scalable-distributed-arbitration technique, and a WDM interconnection system that connects all 80-Gbit/s switching modules is developed. Using these components: an experimental 640-Gbit/s switching system is partially constructed. It can be applied to realize future broadband ATM networks
