Abstract (en)
[origin: WO03071746A1] The invention relates to a method for protection of label-switching paths in an MPLS network, comprising several nodes connected by IP connections, each path passing through a given series of nodes and connections in said network called elements of said pathway. An element in a first pathway is protected by means of a pathway called the first pathway bypass, starting at a node in the first pathway upstream of said element for protection and terminating at a node of the first pathway downstream of said element for protection with a certain number of network resources being reserved for said first pathway bypass, the latter begin activated in the case of failure of said element in the first pathway. An element in the second pathway is protected by a pathway called the second pathway bypass, starting from a node in the second pathway upstream of said element and terminating at a node of the second pathway downstream of said element. The pathway of the bypass for the second pathway uses at least a part of the resources reserved for the pathway of the first pathway bypass.
