ABSTRACT:
A method for locating a fault in a communication network, includes receiving status information relating to alarms, events, polled statuses or test results in the communication network; and locating the fault based on the received status information, wherein locating the fault includes identifying a limited region of the communication network in which the fault has occurred based on the received status information and on topological and functional information relating to network apparatuses that have generated the status information; constructing a probabilistic model relating faults and status information in the identified limited region of the communication network; and locating the fault based on the constructed probabilistic model and on status information received from the identified limited region of the communication network.
