    • Técnicas para minimizar la degradación provocada por la polarización en las comunicaciones por fibra óptica 

      Comellas Colomé, Jaume (Universitat Politècnica de Catalunya, 1999-07-16)
      Tesi
      Accés obert
      En els últims anys la importància de la polarització en les comunicacions òptiques ha crescut notablement com resultat de tres grans desenvolupaments:<br/>1. L'aparició de l'amplificació òptica ha fet que es produeixi un ...
    • Three years of an intensive programme: experiences, observations and learning points 

      Myrup Pedersen, Jens; Gutiérrez López, José Manuel; Kirikova, Marite; Zabludowski, Lukasz; Comellas Colomé, Jaume (Aalborg University Press, 2015)
      Text en actes de congrés
      Accés obert
      This paper summarizes valuable experiences and learning points from three years of the Erasmus funded Intensive Programme on “Implementing Europe’s Future Broadband Infrastructure”. The programme consisted of a course held ...
    • Using dual-path allocation for partial traffic protection in elastic optical networks 

      Junyent Giralt, Gabriel; Comellas Colomé, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Multi-path allocation has been proposed as a simple way to achieve traffic protection in different networking domains. In this work dual-path allocation is proposed for Elastic Optical Networks (EON) assuming dynamic offered ...
    • 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 ...
    • Using spectrum management techniques to differentiate services in elastic optical networks 

      Comellas Colomé, Jaume; Asensio Garcia, Adrian; Ruiz Ramírez, Marc; Junyent Giralt, Gabriel; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Elastic Optical Networks (EONs) have emerged as a promising solution to cope with the growth and heterogeneity of networks data traffic. Nevertheless, several problems arise in dynamic scenarios, being spectrum fragmentation ...
    • Using static connections to improve elastic optical networks performance 

      Comellas Colomé, Jaume; Vicario, L.; Junyent Giralt, Gabriel (Optical Society of American (OSA), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Network resources are poorly used in Elastic Optical Networks under dynamic traffic conditions. A hybrid scheme where some resources are statically allocated and the remaining ones are devoted to dynamic traffic, is proposed ...
