A method for restoring a virtual path, provisioned between a source and a target
node, in a mesh zoned optical network is described. The method, in one embodiment,
broadcasts or floods restore path requests in the network to expedite the identification
of an alternate route and minimize the service disruption for failed virtual path.
The flooding of requests is controlled to ensure efficient performance of the network
yet guaranteeing minimum restoration time to allow critical telecommunication related
traffic to flow through the network with virtually no interruption. The constant
update of nodal topology by each node allows a fast identification of alternate
physical path for failed virtual path.
