Abstract

L’invention concerne un procédé pour détecter l’état de la configuration du chemin du nœud opposé, lequel procédé comprend : la mise en place de l’indicateur d’état pour identifier l’état de configuration de ce chemin pour le nœud opposé par rapport à la configuration du chemin pour le nœud en cours ; l’actualisation de l’indicateur d’état selon l’état de configuration de ce chemin pour le nœud opposé ; la détermination de l’état de la configuration de ce chemin pour le nœud opposé selon ledit indicateur d’état. De plus, un procédé destiné à établir une connexion AAL2 adopte : la mise en place préalable de l’indicateur d’état pour le chemin de configuration pour le nœud ; lors de l’établissement d’une connexion AAL2 entre le nœud en cours et le nœud opposé, la requête de l’indicateur d’état du chemin correspondant de sa propre configuration, lorsque l’indicateur d’état est l’indicateur ayant été configuré, l’établissement de la connexion à l’aide de ce chemin ; dans le cas contraire, l'établissement de la connexion sans utiliser ce chemin. Étant donné qu'il peut savoir si le chemin correspondant est configuré pour le nœud opposé avant d’établir la connexion, il peut ainsi éviter efficacement les tentatives de connexion infructueuses dues à la non coïncidence de la configuration des ressources des deux nœuds de fin et grandement améliorer le taux de réussite des connexions.
