La présente invention concerne un procédé et un appareil pour gérer une défaillance de service de fonction de réseau virtualisée (VNF), utilisés pour résoudre le problème d'impossibilité d'association et de localisation rapides d'une défaillance de service de VNF et d'une ressource d'infrastructure de virtualisation de fonction de réseau (NFVI) lorsqu'une défaillance de service ou d'application est trouvée par un système de gestion d'élément (EMS) classique sous un système de virtualisation de fonction de réseau (NFV). La présente invention consiste à : acquérir des informations de défaillance de service envoyées par un élément de VNF, les informations de défaillance de service transportant un identificateur d'une première machine virtuelle dans laquelle une défaillance apparaît, la première machine virtuelle étant une machine virtuelle configurée pour l'élément de VNF par un gestionnaire de fonction de réseau virtualisée (VNFM) (S21) ; acquérir, selon une relation de mappage présauvegardée entre un identificateur d'une machine virtuelle et des informations de ressource de NFVI, des premières informations de ressource de NFVI correspondant à l'identificateur de la première machine virtuelle (S22) ; et déterminer, selon les premières informations de ressource de NFVI, un dispositif dans lequel une défaillance apparaît (S23). Des modes de réalisation de la présente invention permettent à un utilisateur de localiser rapidement, selon une défaillance de service de VNF, un dispositif dans lequel une défaillance apparaît.
