Drop cost and wavelength optimal two-period grooming with ratio 4
Jean-Claude Bermond, Charles J. Colbourn, Lucia Gionfriddo +2
We study grooming for two-period optical networks, a variation of the traffic grooming problem for WDM ring networks introduced by Colbourn, Quattrocchi, and Syrotiuk. In the two-p…

Traffic Grooming in Bidirectional WDM Ring Networks
Jean-Claude Bermond, Xavier Muñoz, Ignasi Sau Valls
We study the minimization of ADMs (Add-Drop Multiplexers) in optical WDM bidirectional rings considering symmetric shortest path routing and all-to-all unitary requests. We precise…
