Method and apparatus for policy-based alarm notification in a distributed network management environment
First Claim
1. In a distributed network management environment including a plurality of network management servers (12), each server performing fault monitoring for a plurality of network entities in an associated network segment (174, 176) and generating alarms, a method of processing such alarms generated by the plurality of servers characterized in that:
- sending the alarms from the plurality of servers to an alarm monitor (14);
assigning a policy to one or more associated applications (24), the policy comprising a plurality of filters and each filter including at least one filter parameter;
the alarm monitor receiving the alarms from the plurality of servers and applying the policy to the alarms to determine a critical alarm which passes at least one filter, and the alarm monitor sending to the at least one associated application (24) an alarm notification identifying the critical alarm and the at least one filter passed by the critical alarm.

Abstract
Apparatus and method for receiving alarms from multiple network management servers and applying a plurality of policy-based filters to the alarms. The filters may be named and stored in a database, and application of the policy-based filters may be scheduled for different times. The same policy-based filters may be applied to one or more multiple network management applications. The invention allows greater control over which alarms get reported to network management applications and provides a means to ensure consistency of reported alarms across multiple network management applications. A telephonic alarm notification method and apparatus incorporates the policy-based filters and the capability to process alarms from multiple network segment servers so that users can be accurately notified of critical alarms generated in large and complex communications networks, via a public communications system.
