      IST project NOBEL2 results on resilience strategies for next-generation optical transport networks are presented, paving the way towards cost-effective, scalable and easy-to-maintain multi-service network architectures.

    • Traffic variation-aware networking for energy efficient optical communications 

      Morea, Annalisa; Perelló Muntan, Jordi; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      'Traffic-aware' networking is a solution allowing the improvement of the energy efficiency of optical networks. The implementation of these networking schemes makes possible to adapt the number of fully powered systems to ...

    • Using spatial division multiplexing to avoid fragmentation in flex-grid optical networks 

      Comellas Colomé, Jaume; Perelló Muntan, Jordi; Solé Pareta, Josep; Junyent Giralt, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Text en actes de congrés
      Accés obert
      Spectrum fragmentation is one of the main drawbacks of Flex-Grid Optical Networks, and it becomes especially harmful under dynamic traffic conditions. When evolving from single fibre networks to spatial division multiplexed ...

    • Using spectrum fragmentation to better allocate time-varying connections in elastic optical networks 

      Sayyad Khodashenas, Pouria; Comellas Colomé, Jaume; Spadaro, Salvatore; Perelló Muntan, Jordi; Junyent Giralt, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2014-05-01)
      Article
      Accés restringit per política de l'editorial
      Elastic optical network (EON) technology arises as a promising solution for future high-speed optical transport, since it can provide superior flexibility and scalability in the spectrum allocation for seamlessly supporting ...

    • Virtual network embedding in optical infrastructures 

      Pagès Cruz, Albert; Perelló Muntan, Jordi; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Optical network virtualisation has recently become a hot topic among the research community due to its potential to enable the shaping of the Infrastructure as a Service (IaaS) concept. A major challenge that arises of ...
