  • REOURCE ID resource identification
  • SDN Software Defined Network
  • SDN is a new type of network architecture that constructs an open and programmable network architecture by decoupling network control from network forwarding.
  • SDN aims to define the network interconnection and network behavior and open interfaces to support future innovations in various new network architectures and new services.

Abstract

La présente invention concerne un procédé et un dispositif de configuration de RESOURCE ID. Le procédé consiste à : générer un RESOURCE ID pour une ressource et l'envoyer à un dispositif ; recevoir le RESOURCE ID rapporté par le dispositif et le transmettre à une application supérieure. Le RESOURCE ID comprend des informations de type de la ressource et des informations d'entité correspondante. En réduisant le nombre d'interfaces interactives, la présente invention résout le problème selon lequel divers types de ressources correspondent à différentes structures d'entité, ce qui supprime la nécessité d'attribuer des RESOURCE ID de manière centralisée. La présente invention est avantageuse pour le développement d'applications. Elle améliore la flexibilité du déploiement et son efficacité.
