Abstract

La présente invention concerne un procédé pour le traitement de redémarrage progressif protocole RSVP lors du redémarrage simultané d'une pluralité de noeuds voisin comprenant les étapes suivantes; (1) le noeud de redémarrage annonce la capacité de redémarrage progressif de protocole RSVP à ses voisins; (2) le déclenchement de redémarrage progressif du protocole RSVP pour la mise en oeuvre du procédé de récupération lors du démarrage simultané d'une pluralité de noeuds voisins. La présente invention introduit une technique d'adresse de multidiffusion ou une technique de mise en attente de données d'urgence clés, qui permettent au noeud en redémarrage d'annoncer sa capacité de redémarrage progressif à ses voisins de sa propre initiative selon le procédé susmentionné. En outre, l'invention introduit le mécanisme correspondant de sorte que le redémarrage progressif de protocole RSVP est activé pour supporter le redémarrage simultané de la pluralité de noeuds voisins, et la récupération, améliorant ainsi la fiabilité du dispositif.
