Abstract
According to an aspect of the invention, an MPLS tunnel identification method includes: establishing MPLS tunnels with an opposing node by distributing an MPLS tunnel label; and determining an MPLS tunnel to be associated with a pseudo wire corresponding to a pseudo wire label among the MPLS tunnels when the pseudo wire label is assigned from the opposing node thereby to notify identification information of the MPLS tunnel together with identification information of the pseudo wire to the opposing node.
Claims7
A method for identifying a Multi-Protocol Label Switching (MPLS) tunnel, the method comprising the steps of:
- establishing, by a first node, MPLS tunnels with an second node;
- assigning, by the second node, a pseudo wire label to the first node, independently of the step of establishing, by a first node, MPLS tunnels with an opposing second node;
- determining, by the first node, an MPLS tunnel from among the established MPLS tunnels associated with a pseudo wire corresponding to the pseudo wire label;
- and
- notifying, by the first node, identification information of the determined MPLS tunnel together with identification information of the pseudo wire associated with the determined MPLS tunnel to the second node.
