  • Load-balanced wavelength assignment strategies for optical burst/packet switching networks 

    Agustí Torra, Anna; Cervelló Pastor, Cristina; Fiol Mora, Miquel Àngel (2009-03)
    Article
    Restricted access - publisher's policy
    Loss-free schemes are defined to ensure successful packet/burst transmissions in optical packet/burst switching networks. To this end, they rely on a collision-free routing and wavelength assignment (CF-RWA) scheme ...
  • On the feasibility of collaborative green data center ecosystems 

    Agustí Torra, Anna; Raspall Chaure, Frederic; Remondo Bueno, David; Rincón Rivera, David; Giuliani, Giovanni (Elsevier, 2015-02-01)
    Article
    Open Access
    The increasing awareness of the impact of the IT sector on the environment, together with economic factors, have fueled many research efforts to reduce the energy expenditure of data centers. Recent work proposes to achieve ...
  • Performance analysis of the sent-but-sure strategy for optical burst and packet switched networks 

    Agustí Torra, Anna; Cervelló Pastor, Cristina; Fiol Mora, Miquel Àngel (2010-09-21)
    Article
    Restricted access - publisher's policy
    This work proposes an analytical model to characterize the performance of a loss-free transmission strategy for Optical Burst and Packet Switched Networks, which ensures that a burst/packet will successfully reach its ...
  • SDN-based management of time-sensitive networks in 5G fronthaul 

    Castaño, Feliu; Castaño, Oriol; Anangonó, Gabriel; Rincón Rivera, David; Agustí Torra, Anna (2018)
    Conference report
    Restricted access - publisher's policy
    Software Defined Networking is a key element in the 5G architecture, as it allows a more flexible, dynamic network management. Cloud RAN is another enabler of 5G, due to the expected increased based station density in the ...
