    • Experimental assessment of in-operation spectrum defragmentation 

      Gifre Renom, Lluís; Paolucci, Francesco; Aguado, Alejandro; Casellas Regi, Ramón; Castro Casales, Alberto; Cugini, Filippo; Castoldi, Piero; Velasco Esteban, Luis Domingo; López Grimau, Víctor (2014-06-01)

      Dynamic operation of flexgrid networks might cause optical spectrum to be divided into fragments, which makes it difficult finding contiguous spectrum of the required width for incoming connection requests, leading thus ...
    • First experimental assessment of ABNO-driven in-operation flexgrid network re-optimization 

      Gifre Renom, Lluís; Paolucci, Francesco; Velasco Esteban, Luis Domingo; Aguado, Alejandro; Cugini, Filippo; Castoldi, Piero; López Álvarez, Victor (2015-02-01)
      Article
      Open Access
      Traffic affected by link failures can be recovered using path restoration schemes. In dynamically operated networks provided with a control plane, restoration algorithms run in a centralized element, such as the path ...
    • First experimental demonstration of ABNO-driven in-operation flexgrid network re-optimization 

      Velasco Esteban, Luis Domingo; Paolucci, Francesco; Gifre Renom, Lluís; Aguado, Alejandro; Cugini, Filippo; Castoldi, Piero; López, Víctor (The Optical Society (OSA), 2014)
      Conference report
      Open Access
      The after failure repair optimization problem is used to experimentally validate in-operation planning using the ABNO architecture to control a flexgrid optical network. A back-end PCE is used to solve this computational ...
    • LIGHTNESS: a deeply-programmable SDN-enabled data centre network with OCS/OPS Multicast/Unicast switch-over 

      Saridis, JM; Peng, Shpuping; Yan, Yan; Aguado, Alejandro; Buo, Bingli; Arslan, M; Jackson, C; Miao, Wang; Calabretta, Nicola; Agraz Bujan, Fernando; Spadaro, Salvatore; Bernini, Giacomo; Ciulli, Nicola; Zervas, G; Nejabati, Reza; Simeonidou, Dimitra (Institute of Electrical and Electronics Engineers (IEEE), 2015)
