ABSTRACT:
In one aspect, a method for identifying faults in a network that has generated a plurality of fault alarms is provided. A plurality of object/alarm pairs are generated and an identification vector is assigned to each pair. The pairs are processed based on a set of rules to generate for each pair an alarm propagation vector that identifies that pair together with any other pairs from the plurality of pairs. The alarm propagation vectors are processed to determine which pairs have alarm propagation vectors that are not sub vectors of any of the alarm propagation vectors of the other pairs. Any pairs thus determined are identified as being linked to potential root causes of network problems.
