Abstract
A service modification method includes, in a node which is part of a network controlled by a control plane, routing a connection off of its home path to a current path which is at least partially disjoint from the home path and creating a reservation for the connection on the home path such that the connection can revert thereto; signaling a modification of the connection while it is on the current path; and updating the reservation based on the modification including signaling the modification to all nodes on the home path. The service modification method can further include reverting the connection to the home path with the modification. The updating can fail due to an inability to support the modification on the home path, and the service modification method can further include periodically retrying the updating the reservation based on the modification.
