Abstract

Un mode de réalisation de la présente invention concerne un procédé d'autorisation de ressources destiné à un déploiement VNF, un gestionnaire de fonction de réseau virtuel (VNFM), un orchestrateur de fonction de réseau virtuel (NFVO), un support de stockage, et un dispositif. Le procédé comprend les étapes suivantes : un VNFM détermine s'il existe une demande d'application de ressources ; si tel est le cas, le VNMF transmet, à un NFVO, une demande d'autorisation de ressources ; le VNFM reçoit une réponse d'autorisation de ressources transmise par le NFVO, la réponse d'autorisation de ressources comprenant un résultat d'autorisation de ressources ; et le VNFM traite le résultat d'autorisation de ressources.
