Abstract

Apparatus and method for distributed object filtering of objects transferred between a client and server. The objects may be alarms transferred between a network management server and one or more network management applications. The apparatus and method further includes 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 system and method provides increased performance and reliability of passing objects from a server to a client application.

Claims

1. A method of distributed object filtering comprising the steps of:

(a) generating alarms from multiple network management servers;

(b) assigning policy-based filters to both the network management servers and associated network management applications; and

(c) applying the assigned policy-based filters to the alarms and for the alarms which pass the filters, generating an alarm notification and forwarding the same to the associated network management application.

2. An apparatus for distributed object filtering comprising:

a database of policy-based filters;

a user interface for assigning policy-based filters to both a plurality of network management servers and associated network management applications;

a processor and a memory device containing a program of instructions for the processor which instructions include;

means for receiving alarms from the plurality of network management servers;

means for applying, at both the plurality of network management servers and associated network management applications, policy-based filters to the alarms and generating an alarm notification for those alarms which pass the filters; and

means for forwarding the alarm notification to the associated network management applications.
