      Accés restringit per política de l'editorial
      We introduce the problem of reoptimizing the network after a link failure has been repaired as an effective way for reducing capacity usage and improving network performance. Numerical results show gains higher than 42%.

    • How national IP/MPLS networks can benefit from flexgrid optical technology? 

      Velasco Esteban, Luis Domingo; Wright, Paul; Lord, Andrew; Junyent Giralt, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2013)

      Accés obert
      We design a 1113-node network and show that the optimum is a large Flexgrid core serving small metro areas. Cost savings of about 31% in the core and 23% in the metro are shown.

    • Impact of multi-wavelength sliceable transponders in elastic optical networks 

      Dallaglio, Mateo; Giorgetti, Alessio; Sambo, Nicola; Velasco Esteban, Luis Domingo; Castoldi, Piero (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés obert
      The utilization of sliceable bandwidth variable transponders based on multi-wavelength technology is evaluated in EONs. A routing and spectrum assignment scheme is proposed specifically designed to consider the constraints ...

    • Inter-core crosstalk impact on migration planning from elastic optical networks to spectrally-spatially flexible optical networks 

      Lechowicz, Piotr; Rumipamba Zambrano, Rubén Darío; Perelló Muntan, Jordi; Spadaro, Salvatore; Walkowiak, Krzysztof (Optical Society of American (OSA), 2019)
      Text en actes de congrés
      Accés obert
      We study inter-core crosstalk (ICXT) impact on migration planning toward spectrally-spatially flexible optical networks considering 22-core multi-core fiber. Results reveal that 55-70% of links need to be upgraded when ...
