Abstract

L'invention concerne un noeud central (400) de réseau en boucle comprenant un accès de noeud central équipé d'un mécanisme d'insertion d'initialisation de boucle. Par ce mécanisme, un accès de noeud central (400) décelant une nouvelle connexion d'accès de noeud central fournit automatiquement des données d'initialisation de boucle. L'accès en question (400) continue à fournir les données considérées jusqu'au moment où il (400) reçoit une séquence d'initialisation de boucle. Les données d'initialisation de boucle sont transmises le long de la boucle du noeud central, interrompant le traitement normal. Ainsi, la boucle entière est libérée. A la réception d'une séquence d'initialisation de boucle, l'accès de noeud central qui est à l'origine des données d'initialisation de boucle insère le nouvel accès de noeud dans la boucle. Dès lors, l'initialisation de boucle est lancée et chaque accès de noeud (408) dans le réseau en boucle dispose d'une adresse de réseau en boucle unique.
