  • 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 ...
  • 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

    Conference lecture
    Open Access
    Desde el ICE de la UPC se ha planteado una nueva formación dirigida a todo el profesorado basada en la adquisición de competencias docentes. Uno de los módulos de formación puesto en marcha trabaja la adquisición de la ...
  • Experimental assessment of an SDN-based control of OPS switching nodes for intra-data center interconnect 

    Agraz Bujan, Fernando; Miao, Wang; Ferrer Delgado, Alejandro; Bernini, Giacomo; Dorren, Harm; Calabretta, Nicola; Ciulli, Nicola; Perelló Muntan, Jordi; Peng, Shuping; Zervas, Georgios; Simeonidou, Dimitra; Junyent Giralt, Gabriel; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    An SDN-based control framework for OPS switches is experimentally assessed. The OpenFlow messages enabling control communication between SDN controller and OPS switch are validated. Dynamic OPS virtual network slices for ...
  • A novel SDN enabled hybrid optical packet/circuit switched data centre network: the LIGHTNESS approach 

    Peng, Shuping; Simeonidou, Dimitra; Zervas, George; Spadaro, Salvatore; Perelló Muntan, Jordi; Agraz Bujan, Fernando; Careglio, Davide; Becerra Fontal, Yolanda; Farreras Esclusa, Montserrat (2014)
    Conference report

    Current over-provisioned and multi-tier data centre networks (DCN) deploy rigid control and management platforms, which are not able to accommodate the ever-growing workload driven by the increasing demand of ...
  • Impact of transponders and regenerators wake-up time on sleep-mode enabled translucent optical networks 

    Pagès Cruz, Albert; Tornatore, Massimo; Perelló Muntan, Jordi; Spadaro, Salvatore; Morea, Annalisa (2014)
    Conference report
    Restricted access - publisher's policy
    Sleep-mode enabled transponders and regenerators yield to substantial energy savings; however, their non-negligible wake-up time may degrade the network performance. We show that an appropriate dimensioning of the devices ...
