A scheme for sharing a common virtual connection identifier between end-nodes, which enable sharing of a common identifier of a sufficient information length at both end-nodes of a virtual connection. In this scheme, the first message containing a first identifier for provisionally identifying a virtual connection commonly between neighboring nodes is exchanged between neighboring nodes, at a time of setting up the virtual connection. Then, the second message containing a second identifier having a larger information size than the first identifier for formally identifying the virtual connection commonly between neighboring nodes, in a form that enables establishing of a correspondence between the first identifier and the second identifier, is exchanged between neighboring nodes through another virtual connection different from the virtual connection to be set up. The correspondence between the first identifier and the second identifier is managed at each node according to the first message and the second message so as to share the second identifier between neighboring nodes.
L'invention est une méthode de mise en commun d'un identificateur de connexion virtuelle entre noeuds terminaux qui permet de mettre en commun un identificateur à longueur d'information suffisante aux deux noeuds terminaux d'une connexion virtuelle. Dans la méthode de l'invention, un premier message contenant un premier identificateur servant à identifier provisoirement une connexion virtuelle entre noeuds voisins est échangé entre ces noeuds au moment de l'établissement de cette connexion virtuelle. Un second message contenant un second identificateur ayant une plus grande longueur d'information que le premier pour identifier formellement la connexion virtuelle entre les noeuds voisins, dans un format qui permet d'établir une correspondance entre le premier et le second identificateur, est échangé entre les noeuds voisins par l'intermédiaire d'une autre connexion virtuelle différente de celle qui doit être établie. La correspondance entre le premier et le second identificateur est gérée à chaque noeud selon le premier et le second message de façon à ce que le second identificateur soit mis en commun entre les noeuds voisins.
