Abstract

Two centralized arbitration schemes are proposed for a large-capacity optical ATM switch: the dual round-robin matching (DRRM) scheme and the centralized multicast contention resolution (CMCR) scheme. The DRRM scheme can only handle unicast cells, while the CMCR scheme can handle both unicast and multicast cells. The DRRM scheme can make over five billion unicast cell forwarding decisions per second with CMOS technology, while the CMCR can make over one billion multicast cell forwarding decisions per second. With an internal speed-up of two, delay performance of the optical ATM switch is close to that of an output-buffered switch
