      As current traffic growth is expected to strain capacity of today¿s metro network, novel content distribution architectures where contents are placed closer to the users are being investigated. In that regard, telecom ...
    • Analysis of performance degradation in sleep-mode enabled core optical networks [invited] 

      Pagès Cruz, Albert; Tornatore, Massimo; Perelló Muntan, Jordi; Spadaro, Salvatore; Morea, Annalisa (Institute of Electrical and Electronics Engineers (IEEE), 2015-03-01)
      Article
      Accés obert
      Energy efficiency is an important target for the management of wavelength-division-multiplexing-based core optical networks. A possible power management strategy for energy-efficient optical networks consists in putting ...
    • Impact of transponders and regenerators wake-up time on sleep-mode enabled translucent optical networks 

      Pagès Cruz, Albert; Tornatore, Massimo; Perelló Muntan, Jordi; Spadaro, Salvatore; Morea, Annalisa (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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 ...
    • Link vs. opto-electronic device sleep mode approaches in survivable green optical networks 

      Perelló Muntan, Jordi; Morea, Annalisa; Spadaro, Salvatore; Tornatore, Massimo (Institute of Electrical and Electronics Engineers (IEEE), 2013)

      Accés obert
      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)
      Article
      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 ...
