<p>An automated and distributed method and apparatus for normalizing a network after restoration begins with end nodes of the restoral route detecting a clearing of alarms after a failure is repaired. After a specified time period is passed, the end nodes perform a sequence of tasks to execute a modified form of a patch-and-roll normalization. Each end node transmits traffic over both the restoral route and the original traffic route that has been fixed. Each end nodes confirms receipt of signals over the fixed traffic route. Thereafter, each end node switches to receiving live traffic from the restoral route to the fixed traffic route and stops transmitting over the restoral route. Finally, the end nodes instruct the other nodes along the restoral route to disconnect the restoral route.</p> |
