Abstract
Telecommunications networks are often managed by a large number of management centers, each responsible for a logically autonomous part of the network. This could be a small sub-network such as an Ethernet, a Token Ring or an FDDI ring, or a large sub-network comprised of many smaller networks. In response to a single fault, in a telecommunications network, many network elements may raise alarms, which are typically reported only to the sub-area management center that contains the network element raising the alarm. As a result, a particular management center has a partial view of the status of the network. Management Centers must therefore cooperate in order to correctly infer the real cause of the failure. The algorithms proposed in this paper, outline the way these management centers could collaborate in correlating alarms and identifying faults.
