    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

    Video streaming on mobile devices is prone to a multi-tude of faults and although well established video Qual-ity of Experience (QoE) metrics such as stall frequencyare a good indicator of the problems perceived by theuser, ...
  • 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
