    • 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)
      Conference report
      Restricted access - publisher's policy
      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 ...

    • Enabling multi-tenancy in hybrid optical packet/circuit switched data center networks 

      Peng, Shuping; Nejabati, Reza; Guo, Bingli; Shu, Yan; Zervas, Georgios; Spadaro, Salvatore; Pagès Cruz, Albert; Simeonidou, Dimitra (2014)
      Conference report
      Restricted access - publisher's policy
      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)
      Conference report
      Restricted access - publisher's policy
      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 ...

      Conference report
      Open Access
      This paper presents a hybrid optical test-bed controlled by a hardware-accelerated control plane capable of dynamically provisioning the most suitable route according to the requirements of the client technology and the ...

    • Multi-service MAC-enabled OBS networks 

      Triay Marquès, Joan; Zervas, Georgios; Cervelló Pastor, Cristina; Nejabati, Reza; Simeonidou, Dimitra (2010-03)
      Conference lecture
      Restricted access - publisher's policy
      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)
      Conference lecture
      Open Access
      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
      Open Access
      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 ...
