    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

    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 ...
  • Demonstration of reconfigurable virtual data center networks enabled by OPS with QoS guarantees 

    Miao, Wang; Peng, Shuping; Spadaro, Salvatore; Bernini, Giacomo; Agraz Bujan, Fernando; Ferrer Ferré, Àlex; Perelló Muntan, Jordi; Zervas, Georgios; Nejabati, Reza; Ciulli, Nicola; Simeonidou, Dimitra; Dorren, Harm; Calabretta, Nicola (Institute of Electrical and Electronics Engineers (IEEE), 2014)

    We demonstrate a reconfigurable virtual datacenter network by utilizing statistical multiplexing offered by scalable and flow-controlled optical switching system. Results show QoS guarantees by the priority assignment and ...
  • Circuit area optimization in energy temporal sparse scenarios for multiple harvester powered systems 

    Gomez Cid-Fuentes, Raül; Cabellos Aparicio, Alberto; Alarcón Cot, Eduardo José (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    Multi-source energy harvesters are gaining interest as a robust alternative to power wireless sensors, since the sensor node can maintain its operation regardless of the fact that one of its energy sources might be temporarily ...
  • Performance evaluation of an all-optical OCS/OPS-Based network for intra-data center connectivity services 

    Pagès Cruz, Albert; Jiménez Feijóo, Sergio; Perelló Muntan, Jordi; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    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 ...
  • Performance analysis of multicast routing algorithms 

    Papadimitriou, Dimitri; Careglio, Davide; Demeester, Piet M.A. (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    This paper provides a theoretical performance analysis of different classes of multicast routing algorithms, namely the Shortest Path Tree, the Steiner Tree, compact routing and greedy routing. Our motivation is to determine ...
