      Accés restringit per política de l'editorial
      In a flattened optical data center network employing hybrid technologies, multi-tenancy is enabled by a new virtual data center embedding method that is equipped with network-aware VM placement exploiting the advanced but ...

    • 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)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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 ...

      Accés restringit per política de l'editorial
      In this paper, a novel multi-service architectural solution based on a MAC protocol for mesh OBS networks is designed and the network performance among TDM services and connectionless burst transmissions is evaluated through ...

    • QoS-Enabled distributed access on optical burst-switched networks 

      Triay Marquès, Joan; Zervas, Georgios; Cervelló Pastor, Cristina; Nejabati, Reza; Simeonidou, Dimitra (IEEE Press. Institute of Electrical and Electronics Engineers, 2010-01)
      Comunicació de congrés
      Accés obert
      Optical Burst Switching (OBS) has been proposed as an efficient technology to cope with the ever increasing bursty traffic on the Internet. The emergence of a broad range of network-driven applications (e.g. multimedia, ...

    • 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)
      Article
      Accés obert
      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 ...
