Abstract

La présente invention concerne un procédé de configuration de commutateur et un dispositif associé. Le procédé de la présente invention consiste à : acquérir une topologie physique entre un commutateur optique et un ensemble de commutateurs électriques; déterminer un trajet d'envoi de service et un trajet de réception de service entre un premier commutateur électrique et un second commutateur électrique dans l'ensemble de commutateurs électriques selon la topologie physique, une interface d'envoi sur le trajet d'envoi de service et une interface de réception sur le trajet de réception de service n'étant pas dans le même groupe d'interfaces physiques; déterminer une interface logique dans le premier commutateur électrique ou le second commutateur électrique en fonction du trajet d'envoi de service et du trajet de réception de service, l'interface logique comprenant l'interface d'envoi sur le trajet d'envoi de service et l'interface de réception sur le trajet de réception de service; et envoyer des premières informations de configuration au premier commutateur électrique ou au second commutateur électrique, les premières informations de configuration étant utilisées pour ordonner au premier commutateur électrique ou au second commutateur électrique de transmettre un service au moyen d'une interface logique locale. Les moyens mentionnés ci-dessus permettent d'obtenir plus de trajets inactifs dans un système pour établir une connexion entre deux commutateurs électriques.
