Abstract
Fault management and providing resilience against failures is an useful for many networks. Protection techniques are used to ensure that networks can continue to provide reliable service and to provide redundant capacity within a network to reroute traffic in presence of a failure. A method or corresponding apparatus according to an example embodiment of the present invention relates to determining availability in a network. The example embodiment calculates availability on a per demand basis for working, protection, and restoration paths among all demands in the network and reports the availability. The reported availability may be used to plan and suggest changes to the network or to recommend addition of equipment to improve the availability of the network while ensuring that service level agreements are satisfied.
