      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 ...

    • Multipath restoration and bitrate squeezing in SDN-based elastic optical networks [Invited] 

      Paolucci, Francesco; Castro Casales, Alberto; Cugini, Filippo; Velasco Esteban, Luis Domingo; Castoldi, Piero (2014-08-01)
      Article
      Accés restringit per política de l'editorial
      Sliceable bandwidth-variable transponders (SBVTs) enable the adaptation of transmission parameters according to traffic requirements and network constraints. In this study, SBVTs capabilities are evaluated in the context ...

    • On the benefits of differentiating the filter configurations in flexi-grid optical networks 

      Castro Casales, Alberto; Cugini, Filippo; Velasco Esteban, Luis Domingo; Castoldi, Piero (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      An effective strategy exploiting differentiated filter configurations in flexi-grid optical networks is proposed and evaluated. Results show that 15% throughput improvements can be achieved with respect to traditional ...

    • Routing, spectrum, and transponder assignment in elastic optical networks 

      Dallaglio, Mateo; Giorgetti, Alessio; Sambo, Nicola; Velasco Esteban, Luis Domingo; Castoldi, Piero (2015)
      Article
      Accés obert
      Backbone networks are evolving toward Elastic Optical Network (EON) architecture that allows a flexible and efficient use of spectrum resources. Flexibility in EONs is guaranteed also by emerging sliceable bandwidth variable ...

    • Signal overlap for efficient 1+1 protection in elastic optical networks (EONs)
