Smart design of multigranular optical switching fabric with traffic grooming

We introduce an intelligent optical cross connect OXC structure based on our lambda-group model, as well as a dynamic algorithm of configuration helpful to compli- cated optical traffic grooming, which presents a distinctive approach of dividing granularities into specific tunnels for ef- fective treatment. Results and figures from experiments show that the particular channel partition not only is helpful to port reduction significantly, but also improves the channel and blocking performance for dynamic connection requests. © 2006 Society of Photo-Optical Instrumentation Engineers.
