Abstract
A method for restoring a virtual path, provisioned between a source and a target node, in a zoned mesh optical network is described. The method, in one embodiment, allocates a primary and a secondary physical path to the virtual path. The two physical paths are node and link disjoint. In case of a failure on one physical path, the network switches the virtual path to the other physical path. The alternate path can be shared among various virtual paths during the restoration.
