  • New trends on Optical Access Networks: DBAs for 10G EPON and Long-Reach PON 

    Gutiérrez González, Lluís; Andrade Jardín, Marilet de; Sallent Ribes, Sebastián (2009-06-10)
    Conference report
    Open Access
    The access network infrastructure plays an important role in the overall performance of the network, next generation access networks (NGA) must be able to access diverse services, and should incorporate adequate architectures ...
  • Next Generation Optical Access Networks: from TDM to WDM 

    Gutiérrez González, Lluís; Garfias Hernandez, Paola; Andrade Jardín, Marilet de; Cervelló Pastor, Cristina; Sallent Ribes, Sebastián (INTECH, 2010-03)
    Part of book or chapter of book

    Wireless LAN is becoming a pervasive wireless access technology that can be found in almost any mobile device such as laptops, PDAs, portable game consoles and mobile phones. Each of these groups of devices have a different ...
  • Optimizing the migration to future-generation passive optical networks (PON) 

    Andrade Jardín, Marilet de; Tornatore, Massimo; Sallent Ribes, Sebastián; Mukherjee, Biswanat (2010-12)
    Article
    Open Access
    We study the upgrading problem of existing Passive Optical Networks (PONs) that need to increase their capacity at different points in time. Our method upgrades line rates and migrates network services over new wavelength ...
  • P4ON: a 5G-aware P4-based PON architecture 

    Haastrup, Adebanjo; Rincón Rivera, David; Khalili, Hamzeh; Sallent Ribes, Sebastián (2018)
    Conference report
    Restricted access - publisher's policy
    5G promises to deliver higher rates with lower latency and fixed-mobile network convergence. Passive Optical Networks (PON) have emerged as a viable option for 5G access and backhaul networks due to their cost effectiveness ...
  • Performance analysis of AND gates based on four-wave-mixing for application in optical-code division multiple access systems 

    Noshad, M.; Noshad, M.; AlaviRad, S.M.; Sallent Ribes, Sebastián (2012-02)
    Article
    Restricted access - publisher's policy
    In this paper, we study the performance of all optical AND gates based on the four-wave-mixing (FWM) process, for application in the receivers of the spectral phase encoded optical code division multiple access (SPE-OCDMA) ...
  • Real-time services in EPON 

    Garfias Hernandez, Paola; Sallent Ribes, Sebastián; Gutiérrez González, Lluís; Camps Mur, Daniel (2012)
    Conference lecture
    Restricted access - publisher's policy
    This paper proposes an improved scheduling algorithm that optimizes the allocation of the real-time services and elastic flows in EPON by spreading the real-time service periods lowering the delay and thus fulfilling the ...
  • Three dimensional adaptive Laplacian Pyramid image coding 

    Sallent Ribes, Sebastián; Torres Urgell, Lluís; Gils, L. (Elsevier, 1990)
    Conference report
    Open Access
  • Toward a holistic federated future Internet Experimentation environment: the experience of NOVI research and experimentation 

    Maglaris, Vasilis; Papagianni, Chrysa A.; Androulidakis, G.; Grammatikou, M.; Grosso, P.; Van der Ham, J.; Sallent Ribes, Sebastián (2015-07-01)
    Article
    Restricted access - publisher's policy
    This article presents the design and pilot implementation of a suite of intelligent methods, algorithms, and tools for federating heterogeneous experimental platforms (domains) toward a holistic Future Internet experimentation ...
