Abstract

The invention includes an apparatus and associated methods for facilitating communication between a managed system and management systems. The apparatus includes at least one protocol agent and a management layer. A protocol agent is adapted for communicating with at least one management system using a protocol. The protocol agent includes at least one protocol entity. The management layer is adapted for facilitating communication between the at least one protocol entity and system hardware including a plurality of physical system entities. The management layer includes a plurality of logical system entities associated with the physical system entities. The management layer supports at least one mapping between the logical system entities of the management layer and the protocol entities of the protocol agent. The apparatus facilitates downstream communications from one or more management systems to the managed system, and upstream communications from the managed system to one or more management systems.

Claims

1. A method, comprising:

receiving a management request from a management system, wherein the management request is formatted using a protocol;

identifying, using the protocol, a protocol agent adapted for processing the management request;

identifying, using the management request, a protocol entity of the identified protocol agent;

identifying a logical system entity associated with the identified protocol entity, wherein the logical system entity is identified using a mapping between the protocol entity and the logical system entity; and

triggering the identified logical system entity to perform a management task specified by the management request.

2. The method of claim 1, further comprising:

updating the identified logical system entity in response to the management request.

3. The method of claim 1, further comprising:

identifying a user associated with the management request;

identifying a user profile associated with the identified user; and

determining, using the user profile, whether the identified user is permitted to access the identified logical system entity to perform the management task specified by the management request.

4. The method of claim 1, wherein the protocol agent comprises a protocol-specific information model associated with the protocol, wherein the logical system entity forms a portion of a protocol-independent information model.

5. The method of claim 1, wherein the mapping between the protocol entity and the logical system entity a mapping between (1) at least one of an object, an attribute, and an attribute value of the protocol entity, and (2) at least one of an object, an attribute, and an attribute value of the logical system entity.

6. The method of claim 1, wherein the management task comprises one of:

configuring a physical system entity associated with the identified logical system entity;

or

retrieving an attribute value associated with a physical system entity.

7. A method, comprising:

updating a logical system entity in response to an attribute value change indication from a physical system entity; and

in response to updating the logical system entity, triggering a protocol entity of a protocol agent to send at least one notification to a management system using a protocol associated with the protocol agent, wherein the protocol entity is triggered using at least one mapping between the logical system entity and the protocol entity.

8. The method of claim 7, wherein updating the logical system entity comprises:

storing the attribute value change indication in at least one cache associated with the logical system entity.

9. The method of claim 7, wherein the at least one mapping between the logical system entity and the protocol entity comprises a mapping between (1) at least one of an object, an attribute, and an attribute value of the logical system entity, and (2) at least one of an object, an attribute, and an attribute value of the protocol entity.

10. The method of claim 7, wherein the logical system entity forms a portion of a protocol-independent information model.

11. The method of claim 7, wherein the protocol agent comprises a protocol-specific information model associated with the protocol, wherein the at least one notification is formatted using the protocol-specific information model.

12. The method of claim 7, wherein triggering the protocol entity of the protocol agent to send the at least one notification to the management system comprises:

receiving the at least one notification from the logical system entity; and

sending the at least one notification to the management system using at least one notification message formatted according to the protocol.

13. An apparatus, comprising:

a protocol agent adapted for communicating with at least one management system using a protocol, wherein the protocol agent comprises a plurality of protocol entities; and

a management layer adapted for facilitating communication between the at least one protocol entity and system hardware comprising a plurality of physical system entities;

wherein the management layer comprises a plurality of logical system entities associated with the physical system entities, wherein the management layer supports at least one mapping between the logical system entities of the management layer and the protocol entities of the protocol agent.

14. The apparatus of claim 13, wherein the protocol agent is further adapted for:

receiving a management request from a management system, wherein the management request is formatted using a protocol associated with the protocol agent;

identifying, using the management request, at least one of the protocol entities;

identifying at least one of the logical system entities, wherein the at least one identified logical system entity is identified using the at least one mapping; and

triggering the at least one identified logical system entity to perform a management task specified by the management request.

15. The apparatus of claim 14, wherein the management layer is further adapted for:

updating the at least one identified logical system entity in response to the management request.

16. The apparatus of claim 14, wherein the management layer is further adapted for:

identifying a user associated with the management request; and

determining whether the identified user is permitted to access the at least one identified logical system entity to perform the management task specified by the management request.

17. The apparatus of claim 13, wherein the management layer is further adapted for:

updating at least one of the logical system entities in response to an attribute value change indication from one of the physical system entities; and

in response to updating the at least one logical system entity, triggering at least one of the protocol entities to send at least one notification to a management system using a protocol associated with the protocol agent, wherein the at least one triggered protocol entity is triggered using the at least one mapping.

18. The apparatus of claim 17, wherein the management layer is further adapted for:

storing the attribute value change indication in at least one cache associated with the at least one triggered protocol entity.

19. The apparatus of claim 13, wherein the at least one mapping between the logical system entities of the management layer and the at least one protocol entity of the protocol agent comprises a mapping between (1) at least one of an object, an attribute, and an attribute value of the logical system entities, and (2) at least one of an object, an attribute, and an attribute value of the protocol entities.

20. The apparatus of claim 13, wherein the protocol agent comprises a protocol-specific information model, wherein the management layer comprises a protocol-independent information model.
