Abstract

Cette invention concerne une technique qui permet de confirmer la concordance d'un système de réseaux et qui consiste à : recueillir des informations spécifiant le fonctionnement de dispositifs constituant des réseaux en tant qu'informations concordantes ; entrer, en tant qu'informations de confirmation sur un réseau renfermant un terminal, un ensemble d'informations concernant la connexion de terminaux opposés, ceci à propos de la connexion entre le terminal et un terminal contenu dans un autre réseau et relié de manière opposée au premier dans l'information de confirmation de concordance ; et saisir et comparer les ensembles d'informations sur des connexions de terminaux opposés à partir des informations de confirmation de concordance dans le but de confirmer la validité de l'opposition des terminaux. Lorsque la personne qui définit les informations d'élaboration crée un ensemble erroné d'informations sur la connexion de terminaux opposés, il est possible de prouver ce défaut de concordance en comparant les ensembles d'informations sur le branchement de terminaux opposés au niveau des terminaux opposés.
