      Cooperative, Connected and Automated Mobility (CCAM) services require precise and reliable localization services able to infer and track the position of a vehicle with lane accuracy. The H2020 5GCroCo project, which trials ...
    • Experimental evaluation of a full-meshed domain abstraction design model for reduced state information dissemination in multi-domain PCE-based WSONs 

      Pagès, Albert; Casellas, Ramon; Perelló Muntan, Jordi; Martínez, Ricardo; Spadaro, Salvatore; Muñoz, Raul (2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      A novel full-meshed domain abstraction model for scalable state information in PCEbased WSONs is presented. We experimentally evaluate the state information update reduction and the blocking improvement with regard to a ...
    • Experimental study on the impact of regenerator placement strategies when dynamically provisioning in translucent GMPLS WSON networks 

      Martínez, Ricardo; Casellas, Ramon; Muñoz, Raul; García Manrubia, Bélen; Pavón Mariño, Pablo; Klinkowski, Miroslaw; Careglio, Davide (Optical Society of America, 2011)
      Text en actes de congrés
      Accés obert
      The impact of the regenerator placement strategies when dynamically provisioning connections in translucent WSON is studied. The evaluation is experimentally conducted in the ADRENALINE testbed in terms of the connection ...
    • Experimental validation of end-to-end GMPLS-enabled restoration in multi-domain transparent WSON 

      Martínez, Ricardo; Casellas, Ramon; Velasco Esteban, Luis Domingo; Agraz Bujan, Fernando; Muñoz, Raul; Spadaro, Salvatore (IEEE Computer Society Publications, 2010)
      Text en actes de congrés
      Accés obert
      Two GMPLS restoration strategies operating at wavelength and link granularities are experimentally validated in a multi-domain WSON. The strategies are qualitatively compared in terms of resource usage, restorability and ...
    • 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 ...
    • Improving IA-RWA algorithms in translucent networks by regenerator allocation 

      Marín Tordera, Eva; Martinez, R; Muñoz, R; Casellas, Ramon; Solé Pareta, Josep (IEEE, 2009)
      Text en actes de congrés
      Accés obert
      In this paper we present the impact of considering regenerator allocation when selecting routes and wavelengths in translucent networks. In the regular operation of translucent networks, i.e. with dynamic traffic, we assume ...
    • 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)
