Abstract

La présente invention concerne un procédé d'équilibrage de la charge d'un élément de réseau et un dispositif de réseau. Le procédé comprend les étapes consistant à : recevoir un message de notification envoyé par une fonction de réseau de virtualisation, VNF, le message de notification étant utilisé pour indiquer des informations de changement de capacité d'un élément de réseau dans un groupe d'éléments de réseau, le groupe d'éléments de réseau comptant au moins deux éléments de réseau de virtualisation ou le groupe d'éléments de réseau comptant au moins un élément de réseau de virtualisation et au moins un élément de réseau physique ; et, sur la base du message de notification, déterminer un facteur de pondération de l'élément de réseau dans le groupe d'éléments de réseau.
