Reconfigurability of multi-star based lightwave LANs

One of the most crucial design issues in the multi-star-based lightwave LAN environment, the system reconfigurability, i.e., the system capability to reconfigure its virtual topology according to different traffic patterns, is discussed. New reconfiguration metrics are defined as functions of the system hardware parameters. A generic fiber assignment algorithm for achieving the maximum reconfigurable physical topology with minimized system cost is introduced. The system designer can use the introduced reconfigurability-hardware considerations for optimizing the system design
