Abstract:
1. A method of estimating restoration capacity in a network, comprising: identifying a circuit in the network; obtaining a desired number of restoration paths for the circuit; based upon the desired number of restoration paths for the circuit, determining the restoration paths using a Dijkstra shortest path algorithm, the restoration paths calculated based upon a user provided percentage of restoration capacity to be deployed on each of the restoration paths; for each link of restoration path, setting a link weight to first high value if a Shared Link Resource Group ID (SLRG ID) of the link is common with SLRG IDs of links in a corresponding shortest maximally diverse path, and if the link weight was not set to the first high value, for each link, setting the link weight to a second high value if any of the SLRG IDs for the link are common with SLRG IDs of links in the circuit.
