    An effective strategy exploiting differentiated filter configurations in flexi-grid optical networks is proposed and evaluated. Results show that 15% throughput improvements can be achieved with respect to traditional ...
  • Superfilter technique in SDN-controlled elastic optical networks 

    Paolucci, Francesco; Cugini, Filippo; Fresi, Francesco; Meloni, Gianluca; Giorgetti, Alessio; Sambo, Nicola; Poti, Luca; Castro Casales, Alberto; Velasco Esteban, Luis Domingo; Castoldi, Piero (Institute of Electrical and Electronics Engineers (IEEE), 2015-02-01)
