    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 ...
  • 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 ...
  • An autonomic traffic classification system for network operation and management 

    Carela Español, Valentín; Barlet Ros, Pere; Mulla Valls, Oriol; Solé Pareta, Josep (2015-07-01)
    Article

    While elastic optical network technologies have emerged as promising solutions for future ultra-high-speed optical transmission, the unavoidable spectral fragmentation problem that appears in such networks significantly ...
  • Energy-oriented denial of service attacks: an emerging menace for large cloud infrastructures 

    Palmieri, Francesco; Ricciardi, Sergio; Fiore, Ugo; Ficco, Massimo; Castiglione, Aniello (2015-05-01)
    Article
    Open Access
    This work analyzes a new and very subtle kind of security threat that can affect large-scale cloud-based IT service infrastructures, by exploiting the computational resources of their component data center to waste as much ...
  • Optimal virtual slice composition toward multi-tenancy over hybrid OCS/OPS data center networks 

    Pagès Cruz, Albert; Pérez Sanchis, Miguel; Peng, Shuping; Perelló Muntan, Jordi; Simeonidou, Dimitra; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2015-10-01)
    Article
    Open Access
    Multi-tenancy is a key feature of modern data centers. It allows for the existence of multiple independent virtual infrastructures, called virtual slices, on top of the same physical infrastructure, each of them specially ...
  • SDN-enabled OPS with QoS guarantee for reconfigurable virtual data center networks 

    Miao, Wang; Agraz Bujan, Fernando; Peng, Shuping; Spadaro, Salvatore; Bernini, Giacomo; Perelló Muntan, Jordi; Zervas, Georgios; Nejabati, Reza; Ciulli, Nicola; Simeonidou, Dimitra; Dorren, Harm; Calabretta, Nicola (Institute of Electrical and Electronics Engineers (IEEE), 2015-07-01)
    Article

    Optical packet switching (OPS) can enhance the performance of data center networks (DCNs) by providing fast and large-capacity switching capability. Benefiting from the software-defined networking (SDN) control plane, which ...
  • LISP: a southbound SDN protocol? 

    Rodríguez Natal, Alberto; Portoles Comeras, Marc; Ermagan, Vina; Lewis, Darrel; Farinacci, Dino; Maino, Fabio; Cabellos Aparicio, Alberto (2015-07-01)
    Article
    Open Access
    The Locator/ID Separation Protocol (LISP) splits current IP addresses overlapping semantics of identity and location into two separate namespaces. Since its inception the protocol has gained considerable attention from ...
