  • 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

  • Quality of network economics optimisation using service level agreement modelling 

    Santos Boada, Germán; Amazonas, José Roberto de Almeida; Solé Pareta, Josep (Wiley-Blackwell, 2016-02-09)
    Article
    Restricted access - publisher's policy
    This paper analyses the relationships between different service level agreement (SLA) components, that is, the different types of quality metrics employed by infrastructure and service providers. We propose that the quality ...
  • Joint content placement and lightpath routing and spectrum assignment in CDNs over elastic optical network scenarios 

    Perelló Muntan, Jordi; Walkowiak, Krzysztof; Klinkowski, Miroslaw; Spadaro, Salvatore; Careglio, Davide (2016-03-01)
    Article
    Restricted access - publisher's policy
    In this work, we address the problem of jointly deciding the placement of the contents delivered by a Content Distribution Network (CDN) among the available data centers, together with the allocation of the lightpaths ...
  • 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 ...
  • Characterization and modeling of multicast communication in cache-coherent manycore processors 

    Abadal Cavallé, Sergi; Martinez, Raul; Solé Pareta, Josep; Alarcón Cot, Eduardo José; Cabellos Aparicio, Alberto (2016-01-21)
    Article
    Restricted access - publisher's policy
    The scalability of Network-on-Chip (NoC) designs has become a rising concern as we enter the manycore era. Multicast support represents a particular yet relevant case within this context, mainly due to the poor performance ...
