International ClassG01R 031/28AbstractAn approach for modeling and solving the problem of fault localization and alarm correlation in large communication networks is presented. Specifically, a new alarm structure is presented along with a general model for representing a communications network. Several specific processing algorithms are provided for solving alarm correlation and fault localization problems in the presence of one or more faults. These algorithms differ in the degree of accuracy achieved in locating a fault, and in the degree of complexity required for implementation.Other References
