    • 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 ...

    • Improving QoT estimation accuracy with DGE monitoring using machine learning 

      Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martinez, Ricardo; Spadaro, Salvatore; Muñoz, Raul (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In optical transport networks, Dynamic Gain Equalizers (DGE) are typically used at each link. A DGE selectively attenuates the channels to compensate the cumulative Erbium Doped Fiber Amplifier (EDFA) gain ripple effect ...

    • Introduction to the ONDM2020 special issue 

      Casellas Regi, Ramon; Muñoz, Raul; Furdek, Marija; Spadaro, Salvatore; Zhu, Zuqing (Institute of Electrical and Electronics Engineers (IEEE), 2021-06-01)
      Article
      Accés obert
      This JOCN special issue includes extended versions of selected papers that were presented at the 24th International Conference on Optical Network Design and Modeling (ONDM2020), which took place virtually on May 18–21, ...

    • 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 ...

    • Modeling filtering penalties in ROADM-based networks with machine learning for QoT estimation 

      Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martinez, Ricardo; Spadaro, Salvatore; Muñoz, Raul (2020)
      Text en actes de congrés
      Accés obert
      Monitoring 3dB bandwidth and other spectrum related parameters at ROADMs provides information about quality of their filters. We propose a machine-learning model to estimate end-to-end filtering penalty for more accurate ...

    • 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 ...

    • The Effects of Optimized Regenerator Allocation in Trans-lucent Networks under Inaccurate Physical information 

      Marín Tordera, Eva; Yannuzzi, Marcelo; Masip Bruin, Xavier; Sánchez López, Sergio; Martínez, Ricardo; Muñoz, Raul; Casellas, Ramon; Maier, Guido (2010-02-04)
