Abstract

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.
