    Sleep-mode enabled transponders and regenerators yield to substantial energy savings; however, their non-negligible wake-up time may degrade the network performance. We show that an appropriate dimensioning of the devices ...

    Energy savings of link and OE device sleep mode approaches are compared in 1:1 protected optical networks, together with a hybrid solution combining both of them. The proposed hybrid solution can decrease network energy ...
  • Optimizing the migration to future-generation passive optical networks (PON) 

    Andrade Jardín, Marilet de; Tornatore, Massimo; Sallent Ribes, Sebastián; Mukherjee, Biswanat (2010-12)
    Accés obert
    We study the upgrading problem of existing Passive Optical Networks (PONs) that need to increase their capacity at different points in time. Our method upgrades line rates and migrates network services over new wavelength ...
