Abstract

In a data processing network with distributed applications a notification is sent from a sender to a receiver via a notification service with which the receiver is registered in order to receive notifications satisfying a predetermined test criterion. The predetermined test criterion includes comparison of at least two values concerning the sender object. Applications include telecommunication networks.

Claims

1. A computer implemented method for sending a notification from a sender object to at least one registered receiver object in a data processing network having distributed applications, said at least one registered receiver object receiving notifications from a notification service indicating that a predetermined test criterion has been satisfied, wherein said method comprises:

sending, from said sender object to said notification service, a set of values comprising at least a first value representing a notification message from said sender object, a second value representing a reference level, and a filter control value that determines if said first value is compared against said second value or a preset reference level;

checking if said set of values satisfies said predetermined test criterion associated with said at least one registered receiver object, wherein said notification service checks said set of values with each registered receiver object; and

sending an alarm message if said predetermined test criterion is satisfied, wherein said notification service sends said alarm message to said receiver object associated with said predetermined test criterion.

2. The method claimed in claim 1, wherein said network comprises a plurality of sender objects, wherein each sender object forwards to the other sender objects at least one particular value representative of information concerning the forwarding sender object, said set of values sent by said sender object to said notification service includes a value which depends on at least one of said particular values received by said sender object, and said comparison is effected between said value which is dependent on at least one of said particular values and a value concerning said sender object.

3. The method claimed in claim 1, wherein said sender object or each sender object is adapted to monitor the operation of a resource and the values compared constitute information representative of the functional status of said resource.

4. The method claimed in claim 1, wherein said predetermined test criterion is defined by said receiver object when it is registered with said notification service.

5. The method claimed in claim 1, wherein said second value represents a reference level that is dependent at least in part on notifications sent from other sender objects.

6. The method claimed in claim 5, wherein said second value is the highest alarm sent by said other sender objects.

7. The method claimed in claim 1, wherein said predetermined criterion comprises at least a greater than or equal to criterion, a less than or equal to criterion and an equality criterion.

8. The method claimed in claim 7, wherein said predetermined test criterion is associated with logical operators.

9. A computer implemented method for sending a notification from a sender object to at least one registered receiver object in a data processing network having distributed applications, said at least one registered receiver object receiving notifications from a notification service indicating that a predetermined test criterion has been satisfied, wherein said method comprises:

sending, from said sender object to said notification service, a set of values comprising a first value representing a notification being sent by said sender object and a second value representing a reference level against which said first value is compared, wherein said second value is dependent at least in part on notifications received from other sender objects;

checking if said set of values satisfies said predetermined test criterion associated with said at least one registered receiver object, wherein said notification service checks said set of values with each registered receiver object; and

sending an alarm message if said predetermined test criterion is satisfied, wherein said notification service sends said alarm message to said receiver object associated with said predetermined test criterion.

10. A computer implemented method for sending a notification from a sender object to at least one registered receiver object in a data processing network having distributed applications, said at least one registered receiver object receiving notifications from a notification service indicating that a predetermined test criterion has been satisfied, wherein said method comprises:

sending, from said sender object to said notification service, a set of values comprising a first value representing a notification being sent by said sender object and a second value representing a reference level against which said first value is compared, wherein said second value is the highest alarm received from other sender objects;

checking if said set of values satisfies said predetermined test criterion associated with said at least one registered receiver object, wherein said notification service checks said set of values with each registered receiver object; and

sending an alarm message if said predetermined test criterion is satisfied, wherein said notification service sends said alarm message to said receiver object associated with said predetermined test criterion.
