Abstract
A method of selecting a restoration path in a mesh telecommunication network is disclosed that advantageously is practical and flexible and may be pre-computed along with a service connection path during the setup of the connection. The information used to select the restoration path can be advantageously distributed among nodes in the network.

1-11. (canceled)
A method of selecting a restoration path in a mesh telecommunication network comprising the steps of:
- deleting links in a graph of the network which are not physically diverse from a service path;
- computing a weight for each remaining link in the graph using an array representing a restoration link capacity needed on each link over possible failures of the service path;
- and
- selecting a restoration path that minimizes the weights for each link in the restoration path.
