<p>Upon detection of a fault, the sender node (8) broadcasts a restoration message that includes a weighted identifier to tandem nodes (2, 4, 6, 12). Upon detection of an incoming restoration message, a tandem node (2, 4, 6, 12) retrieves the weighted identifier from the restoration message and modifies it with a weight associated with the spare link (100, 200) from which the restoration message was received. The modified weighted identifier is reinserted into the restoration message and the message is broadcast downstream. The chooser node (10) compares the weighted identifiers of received restoration messages and selects an alternate route with the best weighted identifier.</p> |
