Abstract

La présente invention concerne un procédé de notification d'une ressource originale et un nœud correspondant. Une entité de service commun (CSE) locale envoie une demande de création de ressource notifiée à des CSE distantes qui ne sont pas encore notifiées en fonction d'une demande de notification d'une entité d'application (AE) associée à la ressource originale et lance un temporisateur. Si la CSE locale reçoit une réponse de réussite indiquant la création réussie de la ressource notifiée, la CSE locale ajoute l'adresse de la ressource notifiée contenue dans la réponse de réussite à un attribut « notifié » de la ressource originale. Si la CSE locale reçoit les réponses de toutes les CSE distantes qui contiennent une réponse de réussite avant l'expiration du temporisateur, le temporisateur est arrêté et une réponse véhiculant une valeur actuelle de l'attribut « notifié » est renvoyée à l'AE. Si la CSE locale reçoit les réponses de réussite de certaines des CSE distantes lors de l'expiration du temporisateur, la réponse véhiculant une valeur actuelle de l'attribut « notifié » est envoyée à l'AE. La CSE locale de la solution technique d'après la présente invention peut notifier une ressource originale sur une AE sur une CSE distante et renvoyer un résultat de notification à l'AE dans le temps, ce qui permet d'éviter le gaspillage de ressources.
