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.
Claims24
An apparatus comprising:
- a plurality of single-domain network management systems (NMSs), a first NMS monitoring status information from a first domain of a communications network, correlating the status information to generate a first intra-domain alarm, and providing as an output the first intra-domain alarm, and a second NMS monitoring a second domain of the communications network and providing as an output a second intra-domain alarm;
- and
- a multi-domain network manager operatively coupled to each of the NMSs, and having an input that receives each of the first and second intra-domain alarms, the multi-domain network manager correlating the first and second intra-domain alarms to generate a result.
A method for managing a communications network that is partitioned into a plurality of domains, comprising the steps of:
- receiving a first intra-domain alarm from a first domain of the network, the first intra-domain alarm being generated in response to a correlation of status information from the first domain of the network;
- receiving a second intra-domain alarm from a second domain of the network;
- and
- correlating the first intra-domain alarm with the second intra-domain alarm to generate an inter-domain alarm.
An apparatus for managing a communications network that is partitioned into a plurality of domains, comprising:
- means for receiving a first intra-domain alarm from a first domain of the network, the first intra-domain alarm being generated in response to a correlation of status information from the first domain of the network;
- means for receiving a second intra-domain alarm from a second domain of the network;
- and
- means for correlating the first intra-domain alarm with the second intra-domain alarm to generate an inter-domain alarm.
