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.
