  • Designing national IP/MPLS networks with flexgrid optical technology 

    Velasco Esteban, Luis Domingo; Wright, Paul; Lord, Andrew; Junyent Giralt, Gabriel (2012)
    Conference report
    Open Access
    We propose a two-step procedure to design flexgrid-based national networks. Locations are first partitioned into a set of metro areas interconnected through a flexgrid optical network. Next, each network is designed ...
  • Evolution from wavelength-switched to flex-grid optical networks 

    Lord, Andrew; Rong Zhou, Yu; Jensen, Rich; Morea, Annalisa; Ruiz Ramírez, Marc (Springer, 2016)

    This book presents advances in the field of optical networks - specifically on research and applications in elastic optical networks (EON). The material reflects the authors’ extensive research and industrial activities ...
  • How national IP/MPLS networks can benefit from flexgrid optical technology? 

    Velasco Esteban, Luis Domingo; Wright, Paul; Lord, Andrew; Junyent Giralt, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Open Access
    We design a 1113-node network and show that the optimum is a large Flexgrid core serving small metro areas. Cost savings of about 31% in the core and 23% in the metro are shown.
  • Planning fixed to flexgrid gradual migration: drivers and open issues 

    Ruiz Ramírez, Marc; Velasco Esteban, Luis Domingo; Lord, Andrew; Fonseca, Daniel; Pioro, Michal; Wessäly, Roland; Fernández-Palacios, Juan Pedro (2014-01)
    Article

    Flexgrid technology has recently been presented as the most promising option for upgrading the currently operating fixed grid optical networks and extending their capacity to be able to deal with the massive traffic volumes ...
  • The dichotomy of distributed and centralized control: METRO-HAUL, when control planes collide for 5G networks 

    King, Daniel; Farrel, Adrian; King, Emiko Nishida; Casellas Regi, Ramon; Velasco Esteban, Luis Domingo; Nejabati, Reza; Lord, Andrew (2019-07)
    Article
    Restricted access - publisher's policy
    Automating the provisioning of 5G services, deployed over a heterogeneous infrastructure (in terms of domains, technologies, and management platforms), remains a complex task, yet driven by the constant need to provide ...
  • The network capacity benefits of Flexgrid 

    Wright, Paul; Lord, Andrew; Velasco Esteban, Luis Domingo (2013)
    Conference report
    Restricted access - publisher's policy
    Wavelength Division Multiplexing (WDM) networks of the future are likely to use Flexgrid, providing operators with additional flexibility when assigning spectrum compared to traditional WDM networks using the 50GHz ITU ...
