Abstract
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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
58 words
A method of alarm notification comprising the steps of: (a) receiving alarms from multiple network management servers; (b) assigning policy-based filters to 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.
Claim 2
Independent Claim
58 words
A method of alarm notification comprising the steps of: (a) receiving alarms from multiple network management servers; (b) assigning policy-based filters to 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.
Claim 3
Dependent Claim
24 words
The method of claim 1, wherein: the assigning step includes assigning a plurality of filters comprising a policy to the associated network management application.
Claim 4
Dependent Claim
40 words
The method of claim 2, wherein: each filter comprises at least one filter parameter; and the applying step comprises performing a logical AND of all parameters within one filter and performing a logical OR between all filters within one policy.
Claim 5
Dependent Claim
21 words
The method of claim 3, wherein: the generating step includes specifying real-time values of each filter parameter in the alarm notification.
Claim 6
Dependent Claim
25 words
The method of claim 2, wherein: the assigning step includes storing a policy name and the associated applications in a database accessible to all servers.
Claim 7
Dependent Claim
16 words
The method of claim 1, wherein: the assigning step includes assigning a tag to each filter.
Claim 8
Dependent Claim
24 words
The method of claim 6, wherein: the generating step includes specifying the tag for the filter which the alarm passed in the alarm notification.
Claim 9
Dependent Claim
16 words
The method of claim 1, wherein: the assigning step includes storing the filters in a database.
Claim 10
Dependent Claim
37 words
The method of claim 1, wherein: the generating step further includes specifying a user name in the alarm notification to enable the application which receives the alarm notification to notify a user having the specified user name.
Claim 11
Dependent Claim
19 words
The method of claim 1, wherein: the assigning step includes scheduling the assigning to occur at a specified time.
Claim 12
Dependent Claim
24 words
The method of claim 1, further comprising: (d) following resolution of an alarm, forwarding an alarm clear message to the associated network management application.
Claim 13
Dependent Claim
20 words
The method of claim 1, wherein: the assigning step includes assigning the same filters to multiple associated network management applications.
Claim 14
Dependent Claim
19 words
The method of claim 1, wherein: the assigning step is performed by a user via a graphical user interface.
Claim 15
Dependent Claim
24 words
The method of claim 1, wherein: the generating step includes generating an alarm notification which contains information about the device which generated the alarm.
Claim 16
Dependent Claim
33 words
The method of claim 1, further comprising: one or more of the network management applications generating an alarm clear message and forwarding the same to the network management server which generated the alarm.
Claim 17
Dependent Claim
83 words
Apparatus for alarm notification comprising: a database of policy-based filters; a user interface for assigning policy-based filters to 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 a plurality of network management servers; means for applying 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.
Claim 18
Dependent Claim
83 words
Apparatus for alarm notification comprising: a database of policy-based filters; a user interface for assigning policy-based filters to 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 a plurality of network management servers; means for applying 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.
Claim 19
Dependent Claim
18 words
The apparatus of claim 16, wherein the user interface comprises means for assigning a tag to each filter.
Claim 20
Dependent Claim
28 words
The apparatus of claim 16, wherein the associated network management applications have models of network entities and means for updating the models upon receipt of the alarm notification.
Claim 21
Dependent Claim
23 words
The apparatus of claim 16, wherein the generating means includes means for specifying realtime values of each filter parameter in the alarm notification.
Claim 22
Dependent Claim
27 words
The apparatus of claim 16, wherein the user interface includes means for storing a policy name and the associated application in a database accessible to all servers.
