Abstract

L'invention concerne un procédé et un appareil de demande de ressources et de création d'instance de VNF. Le procédé comprend les étapes suivantes : une VNF envoie des informations de demande de ressources à un VNFM après que la VNF a déterminé la quantité de ressources à demander, les informations de demande de ressources étant utilisées pour que le VNFM demande des ressources en fonction de la quantité de ressources à demander ; et la VNF reçoit un résultat de demande de ressources renvoyé par le VNFM. On peut réaliser de ceci que pendant le processus de demande de ressources dans les modes de réalisation de la présente invention, l'interaction entre la VNF et le VNFM est introduite, et la VNF est capable de déterminer de manière flexible, en fonction des besoins en ressources, la quantité de ressources à demander, ce qui permet aux ressources demandées par le VNFM de satisfaire de manière flexible des variations dynamiques de besoins en ressources ; de plus, la quantité de ressources à demander est produite de manière dynamique par la VNF, ce qui est donc plus pratique et faisable par rapport au procédé de préparation artificielle d'un fichier de VNFD à l'avance dans l'état de la technique.
