Abstract
A localized repair method in a network using a control plane includes, responsive to a failure on a local repair segment defined on a connection traversing the network, generating a release message in the control plane; attempting a local repair on the local repair segment; if the local repair is unsuccessful, transmitting the release message to redial the connection; and, if the local repair is successful, signaling a new sub-path based on the local repair. A controller and a network are also disclosed.
