Abstract

La présente invention concerne un procédé et un dispositif destinés à afficher un trajet de service pour la correction d'une perturbation d'un réseau, relevant du domaine technique des réseaux. Le procédé consiste à acquérir des informations d'objets concernant deux objets ; à rechercher un trajet de service entre lesdits deux objets conformément aux informations d'objets ; à afficher des éléments de réseau et des liens du trajet de service entre lesdits deux objets. Par ailleurs, le dispositif proposé destiné à afficher le trajet de service pour la correction de perturbations d'un réseau comprend : un module d'acquisition d'informations utilisé pour acquérir des informations d'objets concernant deux objets ; un module de recherche de trajet utilisé pour rechercher le trajet de service entre lesdits deux objets conformément aux informations d'objets ; un module d'affichage de trajet utilisé pour afficher des éléments de réseau et des liens du trajet de service entre lesdits deux objets. Grâce à la recherche et à l'affichage visuel du trajet de service conformément aux informations d'objets fournies par un utilisateur, la présente invention a pour effet de permettre à l'utilisateur d'avoir un aperçu intuitif du trajet de service, cela lui permettant de localiser commodément la perturbation.
