Abstract

La présente invention concerne un procédé et un dispositif de traitement de ressources. Le procédé de traitement de ressources comprend les étapes consistant à : gérer les informations de ressources d'un dispositif de transfert de routage, les informations de ressource comprenant au moins : les identifiants d'une ou de plusieurs ressources du dispositif de transfert de routage et les informations d'attribut de chaque ressource de la ou des ressources ; signaler, selon les informations de ressources gérées, des informations de changement de ressources du dispositif de transfert de routage à un terminal de commande, les informations de changement de ressources étant utilisées par le terminal de commande pour mettre à jour les informations de ressources du dispositif de transfert de routage. La présente invention résout le problème en l'état de la technique d'une faible efficacité de communication entre les dispositifs de transfert de routage et les terminaux de commande en l'état de la technique et d'une forte charge sur les terminaux de commande lors du traitement des changements de ressources des dispositifs de transfert de routage, ce qui permet d'améliorer l'efficacité de communication entre dispositifs de transfert de routage et terminaux de commande et d'abaisser la charge sur les terminaux de commande dans le traitement des changements de ressources des dispositifs de transfert de routage.
