    This paper investigates the benefits of dynamic restoration with service relocation in resilient optical clouds. Results from the proposed optimization model show that service availability can be significantly improved ...
  • Probabilistic-based approach for fast impairments-aware RWA in all-optical networks 

    Velasco Esteban, Luis Domingo; Jirattigalachote, Amo; Monti, Paolo; Wosinska, Lena; Spadaro, Salvatore; Junyent Giralt, Gabriel (IEEE Computer Society Publications, 2010)
    Conference report
    Open Access
    We devised a probabilistic model to compute the number of used wavelengths in every link of a transparent optical network. Based on this model, a novel approach for impairments-aware RWA algorithm is proposed and evaluated.
