Abstract
In a particular embodiment, a method of evaluating a network is disclosed. The method identifies potential failure points between a layer two asynchronous transfer mode network and a layer one Synchronous Optical Network (SONET) network. The method includes identifying a first set of circuit identifiers of inter-nodal links of a layer two asynchronous transfer mode (ATM) network, correlating a second set of circuit identifiers associated with elements of a layer one SONET network, identifying a subset of the first set of circuit identifiers of those inter-nodal links that are mated with each other, and comparing the subset of the first set of circuit identifiers to the second set of circuit identifiers to identify single point of failure elements including interface elements and add drop multiplexer elements.
