<p>A centralized restoration system utilizes preferred routing tables to identify an optimal restoral path for restoring a network from a failure. The preferred routing tables are constructed prior to the failure of the network. This pre-construction of the preferred routing tables prior to network failure substantially diminishes the computational and temporal requirements needed to restore the network at the time of failure. The centralized restoration system is able to account for changes in network topology and configuration. The centralized restoration system builds the optimal restoral path on a link by link basis and examines the availability of links prior to adding the link to the optimal restoral path. Unavailable links are not added to the restoral path.</p> |
