Abstract:
(EN) A method and device for protecting tunnel bandwidth are disclosed. The method for protecting tunnel bandwidth includes the steps of: for a protected tunnel which has at least one Class Type (CT), carrying the CT, which needs to be protected, of the protected tunnel and the corresponding bandwidth by means of a Fast Reroute object; sending the Fast Reroute object to a downstream node, and configuring backup tunnels according to the CT, which needs to be protected, of the tunnel and the corresponding bandwidth configured in the Fast Reroute object by the downstream node. According to the present invention, it is possible to perform the bandwidth protection according to the Class Type of the tunnel.
(FR) L'invention porte sur un procédé et un dispositif de protection de bande passante de tunnel. Le procédé de protection de bande passante de tunnel consiste à : pour un tunnel protégé qui a au moins un type de classe (CT), transporter le CT, qui doit être protégé, du tunnel protégé et la bande passante correspondante au moyen d'un objet de réacheminement rapide; envoyer l'objet de réacheminement rapide à un nœud en aval et configurer des tunnels de secours conformément au CT, qui doit être protégé, du tunnel et à la bande passante correspondante configurés dans l'objet de réacheminement rapide par le nœud en aval.
