Applying optical reconfiguration on ATM switch fabrics

Abstract

Altering the internal structure of an ATM switch fabric, based on the correlation among ports, can be proved to be advantageous in terms of performance, especially in LAN or campus ATM switches, where we witness stronger traffic correlation. Such reconfiguration can be easily performed in the optical domain, using simple optical elements. We prove the performance improvement, by applying data collected from a campus production ATM switch onto our proposed architecture.
