    • Design and assessment of FM-MCFs-suited SDM-ROADMs with versatile spatial group configurations and unified QoT estimator 

      Rumipamba Zambrano, Rubén Darío; Muñoz González, Raül; Casellas Regi, Ramon; Perelló Muntan, Jordi; Spadaro, Salvatore; Elfiqi, Abdulaziz E. (Institute of Electrical and Electronics Engineers (IEEE), 2020-11-15)
      Article
      Open Access
      In this article, we focus on the design of different node architectures suitable for few-mode multi-core fibers (FMMCFs) based networks. Both dimensions, core and mode, open different possible ways to group spatial channels ...
    • Enabling data analytics and machine learning for 5G services within disaggregated multi-layer transport networks 

      Casellas Regi, Ramón; Martínez Rivera, Ricardo Victor; Velasco Esteban, Luis Domingo; Vilalta, Ricard; Pavón Mariño, Pablo; King, Daniel; Muñoz González, Raül (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Conference report
      Open Access
      Recent advances, related to the concepts of Artificial Intelligence (AI) and Machine Learning (ML) and with applications across multiple technology domains, have gathered significant attention due, in particular, to the ...
    • Machine learning assisted EDFA gain ripple modelling for accurate QoT estimation 

      Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martínez Rivera, Ricardo Victor; Spadaro, Salvatore; Muñoz González, Raül (The Institution of Engineering and Technology, 2019)
      Conference report
      Open Access
      Wavelength dependent EDFA gain ripple has an impact on connection's OSNR performance. We propose a machine learning regression model to estimate the end to end gain ripple penalty and to increase QoT estimation accuracy.
    • Modelling multi-vendor transponders performance and optimizing launch power 

      Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martínez Rivera, Ricardo Victor; Spadaro, Salvatore; Muñoz González, Raül (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      We propose physical layer model extensions that capture the performance variations of multivendor transponders and use those with appropriate algorithms to optimize connections’ launch powers. We estimated potential SNR ...
    • 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)
      Conference report
      Open Access
      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 ...
    • Quality of transmission estimator retraining for dynamic optimization in optical networks 

      Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martínez Rivera, Ricardo Victor; Muñoz González, Raül; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2021-04-01)
      Article
      Restricted access - publisher's policy
      Optical network optimization involves an algorithm and a physical layer model (PLM) to estimate the quality of transmission of connections while examining candidate optimization operations. In particular, the algorithm ...
    • Towards an SDN/NFV-based multi-tenant network and cloud testbed for end-to-end 5G services 

      Muñoz González, Raül; Mangues Bafalluy, Josep; Bartzoudis, Nikolaos; Vilalta Cañellas, Ricard; Martínez Rivera, Ricardo Victor; Casellas Regi, Ramon; Baldo, Nicola; Núñez Martínez, José; Requena Esteso, Manuel; Font Bach, Oriol; Payaró Llisterri, Miquel; Henarejos Hernández, Pol; Pérez Neira, Ana Isabel (Wireless World Research Forum (WWRF), 2015)
      Conference report
      Open Access
      5G has a main requirement of highly flexible, ultralow latency and ultra-high bandwidth virtualized infrastructure in order to deliver end-to-end services. This requirement can be met by efficiently ...
