CA 2651864

A method for interconnecting with nested Backbone Provider Bridges (PBB) comprises the following steps: the network is divided into multiple layers, each of which is divided into at least one domain; each domain distributes own service tag; local domain transmits the mapping request including user class ID to the other domain in the same layer; the other domain in the same layer transmits back the service tag corresponding to the user class ID to local domain; local domain establishes and stores the mapping relationship; edge device in each domain learns the MAC addresses. A system and device thereof is also provided.

La présente invention concerne un procédé d'interconnexion avec des ponts de fournisseurs de réseau fédérateur comprenant les étapes suivantes: le réseau est divisé en une pluralité de couches, dont chacune est divisée en au moins un domaine; chaque domaine distribue sa propre étiquette de service; un domaine local transmet la requête de mise en correspondance comprenant un identifiant de classe d'utilisateur à l'autre domaine dans la même couche; l'autre domaine retransmet l'étiquette de service correspondant à l'identifiant de classe d'utilisateur au domaine local; le domaine local établit et assure le stockage de la relation de mise en correspondance; un dispositif périphérique dans chaque domaine apprend les adresses de commande d'accès au support. L'invention concerne également un système et un dispositif correspondants.
