      In recent years, the emergence of the cloud computing has increased the need of resources to support cloud-based services. Therefore, the role of the data centers has become essential. Following the growing of services, ...

    • Fully Synchronous SDN (FSS): towards synchronization-as-a-service in 5G networks 

      Suárez Feijóo, Raúl; Rincón Rivera, David; Agustí Torra, Anna; Sallent Ribes, Sebastián (Unión Científica Internacional de Radio (URSI), 2018)
      Conference report
      Restricted access - publisher's policy
      Many modern telecommunications systems rely on strict timing and synchronization requirements. Synchronous Ethernet (SyncE) and Precision Time Protocol (PTP) are widely used to provide frequency and phase synchronization ...

    • Integration of Optical and Wireless Technologies in the Metro-Access: QoS Support and Mobility Aspects 

      Cervelló Pastor, Cristina; Sallent Ribes, Sebastián; Gutiérrez González, Lluís; Remondo Bueno, David; Nunes, Mario; Sargento, Susana; Cesana, Matteo; Filippini, Ilario; Triay Marquès, Joan; Agustí Torra, Anna; Andrade Jardín, Marilet de (2009-07)

    • 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 ...
