<p>A restoration system for restoring a communications network following a failure of one or more communications network components. The restoration system identifies spare segments and spans of spare segments in the original network configuration, as well as interconnected sub-spans of the identified spans of spare segments. The restoration system assigns a cost to the identified spare spans and spare segments. The costs are based on the cost of connecting a spare span or a segment as part of a restoral route and the cost of fragmenting a spare span. The restoration system uses these assigned costs to select a low cost combination of spare segments and spare spans to use as the restoral route.</p> |
