  • Análisis de guías parcialmente rellenas de dieléctrico mediante el método de los elementos finitos 

    Ferrando Bataller, Miquel; Cruellas Ibarz, Juan Carlos; Cardama Aznar, Ángel; Jofre Roca, Lluís (Unión Científica Internacional de Radio (URSI), 1983)
    Conference report
    Open Access
    The finite element's method is aplied to the study of inhomogenous waveguides of arbitrary cross-section. The fields in the guide are - expanded in a series of bidimensional functions, obtaining a variational expression ...
  • Scalable hybrid path computation procedure for PCE-based 

    Hernández Sola, Guillem; Perelló Muntan, Jordi; Agraz Bujan, Fernando; Spadaro, Salvatore; Comellas Colomé, Jaume; Junyent Giralt, Gabriel (2011)
    Conference report

  • Performance evaluation of an all-optical OCS/OPS-based network for intra-data center connectivity services 

    Pagès Cruz, Albert; Jiménez, Sergio; Perelló Muntan, Jordi; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    As the size of Data Centers (DCs) and the amount of information managed by them grows, nowadays electronic-based intra-Data Center Networks (DCNs) start to become a limiting factor, not providing enough scalability nor ...
  • On the benefits of RINA over programmable optical networks for dynamic and smart resource management 

    Leon Gaixas, Sergio; Perelló Muntan, Jordi; Grasa, Eduard; Careglio, Davide; Spadaro, Salvatore (2015)
    Conference report

    In this paper, we describe the basics of the Recursive InterNetwork Architecture (RINA) and its advantages as a packet transport technology over programmable optical networks. In particular, its seamless integration over ...
  • On the performance of dynamic source aggregation of sub-wavelength connections in EONs 

    Sayyad Khodashenas, Pouria; Comellas Colomé, Jaume; Perelló Muntan, Jordi; Spadaro, Salvatore; Junyent Giralt, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    In elastic optical networks, heterogeneous traffic demands are typically supported by a single type of bandwidth-variable transmitters, which is not always spectrum and cost efficient. In light of this, we recently proposed ...
  • Virtual slices allocation in multi-tenant data centre architectures based on optical technologies and SDN 

    Spadaro, Salvatore; Pagès Cruz, Albert; Perelló Muntan, Jordi; Agraz Bujan, Fernando (Optical Society of American (OSA), 2015)
    Conference report
