Abstract

L'invention concerne un procédé et un dispositif d'obtention de ressources virtuelles destinés à résoudre les problèmes actuels liés à la long délai pour l'obtention de ressources virtuelles et au gaspillage de ressources système au cours du processus d'obtention d'une ressource virtuelle d'une VNF. La VNF envoie une demande d'obtention de modèle de VDU à une VNFM, qui indique un NFVO permettant d'obtenir le modèle de VDU que peut offrir le VIM, et envoie le modèle de VDU obtenu à la VNF ; conformément au modèle de VDU, la VNF calcule et obtient le nombre de VM nécessaires lors de l'application du modèle de VDU, et effectue ensuite une demande au VIM d'obtention des ressources virtuelles correspondant au nombre de VM. Au moyen de cette solution technique, il n'est pas nécessaire que la VNF consulte plusieurs fois un VNFM afin de déterminer le type du modèle de VDU, les interactions de signalisation entre la VNF et le VNFM sont réduites, et l'efficacité d'obtention d'une ressource virtuelle de VNF est améliorée.
