Claim One:
1. A method comprising: receiving a multi-layered network model of a data communications network comprising network elements and network services; receiving at least one set of one or more network elements to determine effects of a failure of each set of the at least one set of one or more network elements; simulating the data communications network and failures of each set of the at least one set of one or more network elements to determine whether the each failed set of the at least one set of one or more network elements are backed-up; quantifying service survivability metrics of the effects on network services caused by the failure of each set of the at least one set of one or more network elements based at least in part on a determination that the each failed set of the at least one set of one or more network elements are not backed-up; and outputting data representing the quantified service survivability metrics of the data communications network.
