Patent ID: 7652983

Claim:
A method for signaling in a mesh telecommunication network comprising: at a predetermined node in the mesh telecommunication network: receiving a request to establish a label switched path through the mesh network; computing a service path and a restoration path; sending a label switched path request along the restoration path requesting reservation of shared resources along the restoration path without allocating the shared resources and wherein the label switched path request includes service path information; and responsive to a determination that the label switched path has been switched to the service path, sending a release request to a plurality of nodes along the restoration path, the release request configured to cause a release of a restoration path resource allocation, the label switched path switched responsive to a repair of a failure of at least one component comprised by the service path, the release request an RSVP-TE protocol request comprising a shared reservation flag configured to cause the release of the restoration path resource allocation without causing a release of reserved resources associated with the restoration path and without causing a removal of the restoration path.
