Abstract: front page image
(EN)A method for implementing master and backup transmission path comprises steps: set backup LSPs for each physical transmission link in Data Communication Network (DCN); and when the physical transmission link fails, transmit the packets that need to be transmitted on the physical transmission link to the backup LSP to transfer. The present invention can enhance the packet transmission reliability of DCN and reduce the maintenance workload and complexity of the master and backup transmission path.
(FR)L’invention concerne une méthode d’implémentation d’un chemin de transmission maître et de sauvegarde comprenant les étapes suivantes : définition de LSP de sauvegarde pour chaque liaison physique de transmission d’un DCN (data communication network, réseau de communication de données) ; et si la liaison physique de transmission ne fonctionne pas, transmission des paquets devant être transmis par la liaison physique de transmission au LSP de sauvegarde pour transfert. La présente invention peut améliorer la fiabilité de la transmission de paquets du DCN et réduire la charge de maintenance et la complexité du chemin de transmission maître et de sauvegarde.
