    • GMPLS-based multidomain restoration: analysis, strategies, policies and experimental assessment 

      Velasco Esteban, Luis Domingo; Agraz Bujan, Fernando; Martínez, Ricardo; Casellas, Ramon; Spadaro, Salvatore; Muñoz, Raul; Junyent Giralt, Gabriel (IEEE Press. Institute of Electrical and Electronics Engineers, 2010-07-01)
      Article
      Accés restringit per política de l'editorial
      A connection spanning, for example, several countries crosses multiple optical backbone networks, each one controlled by different administrators or operators. In this context, the interworking of these networks is thus ...

    • Impact of multi-vendor transponders performance on design margin in optical networks 

      Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martínez, Ricardo; Muñoz, Raul; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2021-01-01)
      Article
      Accés obert
      For reliable and efficient network planning and operation, accurate estimation of Quality of Transmission (QoT) is necessary. In optical networks, a physical layer model (PLM) is typically used as a QoT estimation tool ...

    • Modeling EDFA gain ripple and filter penalties with machine learning for accurate QoT estimation 

      Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martínez, Ricardo; Spadaro, Salvatore; Muñoz, Raul (Institute of Electrical and Electronics Engineers (IEEE), 2020-05-01)
      Article
      Accés obert
      For reliable and efficient network planning and operation, accurate estimation of Quality of Transmission (QoT) before establishing or reconfiguring the connection is necessary. In optical networks, a design margin is ...

    • Peer-to-Peer blockchain-based NFV service platform for End-to-End network slice orchestration across multiple NFVI domains 

      Alemany Prats, Pol; Vilalta Cañellas, Ricard; Muñoz González, Raül; Casellas, Ramon; Martínez, Ricardo (2020)
      Text en actes de congrés
      Accés obert
      This paper presents a non-hierarchical architecture to deploy End-to-End Network Slices in a multi-domain network using an Ethereum-based Blockchain to manage the Network Slicing requests across domains. The use of ...

    • Regenerator allocation in translucent networks under inaccurate physical information 

      Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier; Sánchez López, Sergio; Martínez, Ricardo; Muñoz, Raul; Casellas, Ramon (2009-12-14)
      Text en actes de congrés
      Accés obert
      Optimized regenerator allocation techniques select which of the already installed regenerators in a translucent network must be used in order to maximize the quality of the optical signal while minimizing the opaqueness ...

    • TelcoFog: A unified flexible fog and cloud computing architecture for 5G networks 

      Vilalta, Ricard; López Álvarez, Victor; Giorgetti, Alessio; Peng, Shuping; Orsini, Vittorio; Velasco Esteban, Luis Domingo; Serral Gracià, René; Morris, Donald; Fina, Silvia de; Cugini, Filippo; Castoldi, Piero; Mayoral, Arturo; Casellas Regi, Ramón; Martínez, Ricardo; Verikoukis, Christos; Ricart Muñoz, Raul (2017-08-01)
      Article
      Accés obert
      Telecom operators require cloud computing and storage infrastructures, integrated with their heterogeneous access and transport networks, in order to provide software defined networking (SDN), network functions virtualization ...
