Ethernet provider backbone transport (PBT) paths are controlled utilizing Generalized Multi-protocol Label Switching (GMPLS) signaling protocol. A path between edge nodes is identified by a combination of a VID and destination MAC address in a VID/MAC tuple populated in the forwarding tables of intermediary nodes. To establish the PBT path, a path calculation is performed from the originator node to the terminator node through the network. The originating node then sends a GMPLS label object with a suggested VID/MAC to identify the path to the terminator. The intermediary nodes or bridges forward the object to the terminating node. The terminating node then offers a VID/MAC tuple in a GMPLS label object in response. When the intermediary nodes forward the response from the terminating node to the originator, the appropriate forwarding labels are then installed in the forwarding tables of each node utilizing the associated VID/MAC tuples.

On commande les chemins de transport de dorsale de fournisseur (PBT) Ethernet à l'aide d'un protocole de signalisation de commutation d'étiquettes multiprotocole généralisée (GMPLS). On identifie un chemin entre des noeuds d'extrémité par combinaison d'un VID et d'une adresse MAC de destination dans un tuple VID/MAC chargé dans les tables de transmission de noeuds intermédiaires. Pour établir le chemin PBT, on effectue un calcul de chemin du noeud d'origine au noeud de terminaison via le réseau. Puis, le noeud d'origine envoie un objet d'étiquette GMPLS avec un VID/MAC suggéré afin d'identifier le chemin vers le noeud de terminaison. Les noeuds intermédiaires ou ponts envoient l'objet au noeud de terminaison. Ledit noeud de terminaison fournit ensuite un tuple VID/MAC dans un objet étiquette GMPLS en réponse. Lorsque les noeuds intermédiaires envoient la réponse du noeud de terminaison au noeud d'origine, les étiquettes de transmission appropriées sont ensuite installées dans les tables de transmission de chaque noeud à l'aide des tuples VID/MAC associés.
