Abstract
Following failure of part of the network, a restoration process is carried out. A restoration route around the failed part is selected, and at least a portion of the capacity of links along the restoration route is allocated. The restoration route may be completed without delay. If it can be optimised subsequently, it will be changed, to eliminate any loops, or to use routes further away from the failed part, to avoid congestion close to the failed part.
