Text en actes de congrés
Accés obertThis paper evaluates a centralised impairment-aware path restoration approach for GMPLScontrolled transparent optical networks. Experimental results on a 14-node network test-bed show successful QoT compliant path restoration ... -
On the offline physical layer impairment aware RWA algorithms in transparent optical networks: state-of-the-art and beyond
Azodolmolky, Siamak; Pointurier, Yvan; Klinkowski, Miroslaw; Marín Tordera, Eva; Careglio, Davide; Solé Pareta, Josep; Angelou, Marianna; Tomkos, Ioannis (IEEE Press and Wiley, 2009-02-18)
Text en actes de congrés
Accés obertIn transparent optical networks with no regeneration, the problem of capacity allocation to traffic demands is called "Roting and Wavelength Assignment". Much work on this topic recently has focused on the dynamic case, ... -
Routing and wavelength assignment for transparent optical networks with QoT estimation inaccuracies
Azodolmolky, Siamak; Pointurier, Yvan; Angelou, Marianna; Solé Pareta, Josep; Tomkos, Ioannis (2010)
Text en actes de congrés
Accés restringit per política de l'editorialWe show how inaccuracies of Quality of Transmission (QoT) estimations, caused by imperfect models and lack of monitors in transparent optical networks, can be mitigated using a novel routing and wavelength assignment algorithm.
