    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 ...
  • 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
    Restricted access - publisher's policy
    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 ...
  • 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
    Restricted access - publisher's policy
    Traffic classification is an important aspect in network operation and management, but challenging from a research perspective. During the last decade, several works have proposed different methods for traffic classification. ...
  • Web tracking: Mechanisms, implications, and defenses 

    Bujlow, Tomasz; Carela Español, Valentín; Solé Pareta, Josep; Barlet Ros, Pere (2015-07-28)
    External research report
    Open Access
    This articles surveys the existing literature on the methods currently used by web services to track the user online as well as their purposes, implications, and possible user’s defenses. A significant majority of ...
  • 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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    A Software Defined Networking (SDN)-based architecture, employing optical technologies for multi-tenant data centers (DCs), is firstly discussed. Then, an efficient orchestration algorithm for Virtual Data Centers (VDCs) ...
  • Time-domain analysis of Graphene-based miniaturized antennas for ultra-short-range impulse radio communications 

    Abadal Cavallé, Sergi; Llatser Marti, Ignacio; Mestres Sugrañes, Albert; Lee, Heekwan; Alarcón Cot, Eduardo José; Cabellos Aparicio, Alberto (2015-02-24)
    Article
