Abstract

La présente invention se rapporte au domaine technique de la virtualisation de fonction de réseau. La présente invention concerne un procédé et un dispositif de déploiement de service de réseau. Le procédé consiste : à recevoir un message de requête d'instanciation de service de réseau (NS), le message de requête d'instanciation de NS comprenant un identificateur de descripteur de NS (NSD) et des informations d'identification de spécification de déploiement de NS ; selon le message de requête d'instanciation de NS, instancier des instances de caractéristique de réseau virtuel (VNF) formées par une spécification de déploiement de NS, et instancier des instances de liaison virtuelle (VL) formées par une autre spécification de déploiement de NS ; et à créer des points de connexion selon les spécifications de déploiement de NS, et à connecter les instances de VNF formées aux instances de VL correspondantes de façon à réaliser une instanciation de service de réseau qui est réalisée selon les spécifications de déploiement de service sélectionnées et la VNF d'élément comprise.
