RWA problem with geodesics in realistic OTN topologies

This paper presents a decomposition approach for solving a variant of the routing and wavelength assignment (RWA) problem, in which all connection requests are covered by geodesics, i.e., shortest paths with respect to the number of hops. Our …

Optimisation du routage et de l'affectation de longueurs d'onde sur un réseau de télécommunication par programmation mathématique

This work presents a decomposition approach for solving a variant of the routing and wavelength assignment problem, in which all connection requests are covered by shortest paths with respect to the number of hops. Our variant consists in minimizing …
