Abstract

La présente invention concerne un système de réseau d'accès ouvert SDN/NFV, comprenant un terminal de ligne optique virtuelle (vOLT pour virtual Optical Line Terminal), un dispositif de réseau d'accès ayant une capacité de commutation Openflow, et une unité de réseau optique (ONU pour Optical Network Unit), le terminal vOLT et le dispositif de réseau d'accès étant interconnectés au moyen d'un réseau de commutation Openflow ; le dispositif de réseau d'accès et l'unité ONU sont interconnectés au moyen d'un réseau de distribution optique (ODN pour Optical Distribution Network). La présente invention concerne également un procédé pour un système de réseau d'accès ouvert SDN/NFV pour gérer une unité ONU. En combinant un réseau OVS du réseau SDN et la gestion d'unité ONU classique, l'architecture de réseau ODN primaire peut être entièrement utilisée et le processus de gestion de configuration, de maintenance et de mise à jour de l'unité ONU est simplifié.
