  • 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)

    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 ...
  • Assessment of Flex-grid/SDM backbone networks under inter-core XT-limited transmission reach 

    Perelló Muntan, Jordi; Gene Bernaus, Joan M.; Lázaro Villa, José Antonio; Pagès Cruz, Albert; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report
    Open Access
    In the present paper, we estimate the transmission reach of the optical signals through several state-of-the-art multi-core fibers reported in the literature considering ASE noise and inter-core crosstalk. Using these ...
  • 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 ...
  • Multicast on-Chip traffic analysis targeting manycore NoC design 

    Abadal Cavallé, Sergi; Mestres Sugrañes, Albert; Alarcón Cot, Eduardo José; Cabellos Aparicio, Alberto; Martínez, Raúl (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Conference report

    The scalability of Network-on-Chip (NoC) designs has become a rising concern as we enter the many core era. Multicast support represents a particular yet relevant case within this context and has been the focus of different ...
  • Evaluating the feasibility of wireless Networks-on-Chip enabled by graphene 

    Abadal Cavallé, Sergi; Mestres Sugrañes, Albert; Iannazzo Soteras, Mario Enrique; Solé Pareta, Josep; Alarcón Cot, Eduardo José; Cabellos Aparicio, Alberto (Association for Computing Machinery (ACM), 2014)
    Conference report

    Multicast on-chip communications are expected to become an important concern as the number of cores grows and we reach the manycore era. The increasing importance such traffic flows directly contrasts with the diminishing ...
  • Broadcast-enabled massive multicore architectures: a wireless RF approach 

    Abadal Cavallé, Sergi; Sheinman, Benny; Katz, Oded; Markish, Ofer; Elad, Danny; Fournier, Yvan; Roca, Damian; Hanzich, Mauricio; Houzeaux, Guillaume; Nemirovsky, Mario; Alarcón Cot, Eduardo José; Cabellos Aparicio, Alberto (2015-09)
    Article
    Open Access
    Broadcast traditionally has been regarded as a prohibitive communication transaction in multiprocessor environments. Nowadays, such a constraint largely drives the design of architectures and algorithms all-pervasive in ...
