Abstract

A generic management framework for a network management system enables management services and management agents to be added in use as required. Management services can be loaded or plugged into the framework dynamically. As a result a management structure can be provided which is scalable and dynamic and can evolve as requirements change. Management information is modelled as management beans. Network management adaptors can also be added as required to the framework to support protocols such as HTTP, SSL, RMI, SNMP. Remote applications can thereby control the management beans remotely through different protocols.

Claims

1. The network agent for a telecommunications network, said network agent comprising:

an extensible framework;

one or more managed objects registerable with said framework; and

one or more network adaptors registerable with said framework for a network communications protocol for enabling access to said managed objects; and

at least one of the managed objects being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

2. The network agent of claim 1, comprising a repository service object registrable with said framework, said managed object(s) and/or said network adaptor(s) and/or one or more further service objects being registrable with said repository service object, whereby said managed object and said network adaptors are registerable indirectly with said framework via said repository service object.

3. The network agent of claim 2, wherein said network adaptor(s) comprise network adaptor object(s).

4. The network agent of claim 1, wherein said framework comprises getter and setter properties and implements getter and setter methods for getting and/or setting objects and/or object methods.

5. The network agent of claim 1, wherein a said network adaptor is responsive to a received external request to cause said framework to get a managed object method for said request and to return a subsequent response.

6. The network agent of claim 5 and including repository service object registrable with said framework, said managed object(s) and/or said network adaptor(s) being registrable with said repository service object, whereby said managed object and said network adaptors are registerable indirectly with said framework via said repository service object, said framework referencing said repository service for calling said managed object method.

7. The network agent of claim 4, wherein said framework is arranged to effect add object and remove object functions.

8. A computing system connectable to a telecommunications network, said computing system including an network agent, said network agent including:

an extensible framework;

one or more managed objects registerable with said framework; and

one or more network adaptors registerable with said framework for a network communications protocol for enabling access to said managed objects; and

at least one of the managed objects being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

9. An object-based network agent on at least one storage medium, said network agent comprising:

an extensible framework service object;

one or more managed objects registerable with said framework service; and

one or more network adaptor objects registerable with said framework service for a network communications protocol for enabling access to said managed objects; and

at least one of the managed objects being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

10. A network management system comprising a network agent for a managed system, said network agent comprising:

an extensible framework service object;

one or more managed objects registerable with said framework service; and

one or more network adaptor objects registerable with said framework service for a network communications protocol for enabling access to said managed objects; and

at least one of the managed objects being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

11. A network agent for a communications network, such network agent comprising:

an extensible framework;

one or more managed objects registerable with the framework;

and one or more network communications protocol adaptors registerable with the framework for enabling access to the managed objects;

the framework being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

15. A network agent in accordance with any of claims 11, 12, 13 or 14 and including a repository service object registerable with the framework, each managed object and each network communications protocol adaptor being registerable with the repository service object, whereby each managed object and each network communications protocol adaptor is registerable indirectly with the framework via the repository service object.

16. A network agent in accordance with any of claims 11, 12, 13 or 14 wherein a network communications protocol adaptor is responsive to a received external request to cause the framework to get a managed object for such request and to return a subsequent response for such request.

12. A network agent for a communications network, such network agent comprising:

an extensible framework;

one or more managed objects registerable with the framework;

and one or more network communications protocol adaptors registerable with the framework for enabling access to the managed objects;

at least one of the managed objects being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

13. A network agent for a communications network, such network agent comprising:

an extensible framework;

one or more managed objects registerable with the framework;

and one or more network communications protocol adaptors registerable with the framework for enabling access to the managed objects;

at least one of the network communications protocol adaptors being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

14. A network agent for a communications network, such network agent comprising:

an extensible framework;

a plurality of managed objects registerable with the framework;

and a plurality of network communications protocol adaptors registerable with the framework for enabling access to the managed objects;

the framework being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection;

each of a plurality of the managed objects being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection;

and each of a plurality of the network communications protocol adaptors being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

17. A method of providing agent services via a communications network, such method comprising:

dynamically registering one or more managed objects with an extensible agent framework, such framework being a component of an agent service;

registering one or more network adaptors for network communications protocols with the agent framework;

and enabling access to a managed object via a network adaptor;

at least one of the managed objects being a bean which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

18. The method of claim 17 wherein there are a plurality of managed objects registered with the agent framework and a plurality of the managed objects are beans, each of which comprises a set of properties, a set of methods for performing actions, and support for events and for introspection.

19. The method of claim 17 wherein the agent framework comprises an associated repository service object and the registering operations comprise registering each managed object and each network adaptor with the repository service object.

20. The method of claim 17 wherein a network adaptor is responsive to a received external request to cause the agent framework to call a managed object for such request and to return a subsequent response for such request.
