Abstract

La présente invention concerne un procédé de commutation d'interface de réseau d'unité de réseau optique (ONU) et une ONU, le procédé comprenant les étapes suivantes : une ONU surveille un état de liaison entre une interface côté réseau actuellement utilisée et un dispositif de réseau de destination ; détermine une interface côté réseau cible dans au moins une interface côté réseau en attente lorsqu'elle détermine de commuter l'interface côté réseau actuellement utilisée selon ledit état de liaison ; et commute l'interface côté réseau actuellement utilisée vers l'interface côté réseau cible. Sur la base d'une interface de réseau optique passif d'origine (PON), une ou plusieurs interface(s) parmi des interfaces ETH d'origine est/sont activée(s) en tant qu'interface(s) pouvant être utilisées en tant qu'interface côté réseau, de sorte que lorsque l'interface côté réseau actuelle doit être commutée, la commutation peut être faite directement vers une interface côté réseau en attente, ce qui améliore la fiabilité du service de porteuse d'ONU sans qu'il soit nécessaire d'augmenter les coûts matériels, et permet également une mise en réseau plus simple et plus facile à mettre en oeuvre. L'invention concerne également une nouvelle manière de déployer des interfaces côté réseau. Ladite manière d'utiliser une interface ETH en tant qu'interface côté réseau rend la mise en réseau dans son ensemble plus souple et variable.
