Abstract
A multi-domain network manager provides alarm correlation among a plurality of domains included in a communications network. Individual network management systems each monitor a single respective domain of the communications network, and provide intra-domain alarms indicative of status specific to the single respective domain. The multi-domain network manager receives the intra-domain alarms, and correlates them to provide inter-domain alarms as well as responses in the form of corrective actions. The multi-domain network manager thus provides a high level of correlation and response for the entire network while each network management system provides a lower level of correlation and response for an individual domain of the network.
