Abstract

L'invention concerne un procédé et un système permettant d'extraire et d'élaborer une information de route de bout en bout dans un système autonome (AS) de protocole Internet (IP) à zones multiples, à deux niveaux fonctionnant selon un protocole de routage d'état à liaison unique, tel que le système intégré par rapport au protocole de système intégré (IS-IS). Ce procédé et ce système permettent à un utilisateur, tel qu'un administrateur de réseau, d'identifier explicitement un ensemble complet de voies (liaisons et routeurs) que traverserait potentiellement un paquet IP donné de son point d'entrée dans la zone du système autonome, d'où il provient, à son point de sortie dans sa zone de sortie ou au niveau de sa destination prévue.
