Title (EN) METHOD AND APPARATUS FOR SYNCHRONIZING A DATA COMMUNICATIONS NETWORK
(FR) PROCEDE ET APPAREIL DE SYNCHRONISATION D'UN RESEAU DE COMMUNICATION DE DONNEES
Abstract:
(EN) A method is disclosed for synchronizing a data communications network. The data communications network comprises a plurality of existing nodes forming one or more synchronization domains and a node entering the network. Each existing node in a synchronization domain stores a common representation of the synchronization domain and is configured to flood the synchronization domain with domain representation information. In a synchronization domain identification step formed at the entering node, the entering node exchanges entering node domain representation information with a first neighboring existing node. The entering node identifies as a first synchronization domain common with the first neighboring existing node all neighboring existing nodes from which the entering node domain representation information is flooded back to the entering node.
(FR) L'invention concerne un procédé de synchronisation d'un réseau de communication de données comprenant une pluralité de noeuds existants formant au moins un domaine de synchronisation et un noeud entrant dans le réseau. Chaque noeud existant d'un domaine de synchronisation enregistre une représentation commune du domaine de synchronisation et est destiné à envoyer le domaine de synchronisation de données de représentation de domaine. Dans une étape d'identification du domaine de synchronisation au niveau du noeud entrant, le noeud entrant remplace la donnée de représentation du noeud entrant par un premier noeud existant adjacent. Le noeud entrant identifie comme un premier domaine de synchronisation commun par le premier noeud existant adjacent tous les noeuds existants adjacents par lesquels la donnée de représentation de domaine de noeud entrant est renvoyé au le noeud entrant.
