ABSTRACT:
In a self healing network (SHN) distributed restoration algorithm (DRA) scheme, in the case where two adjacent tandem nodes are contending for the same spare link, an arbitration scheme is used to determine which tandem node has the right to reserve the spare link for its use. The arbitration scheme entails a pre-event knowledge by each of the tandem nodes of the transmission time therebetween. A tandem node link arbitration timer in each of the adjacent nodes provides a predefined time period for which a node can compare whether it had begun sending out its flooding signature before the far end node had sent out its. Thus, when a node detects a newly arrived signature received from the spare link that connects the node to its far end node, and if this newly arrived signature is detected before the predefined time period has elapsed, then the node will give up the spare link for the use of the far end node. Alternatively, if the signature, if any, from the far end node is detected by the node only after the predefined time has elapsed, then the node will reserve the connecting spare link for its own use.
