Abstract

Network elements and resources associated with the network elements are manageable by multiple management systems. A request for network element resource management information is transmitted to at least two network management systems, and a reply identifying the network elements that are managed by the respective network management systems from the at least two network management systems is received.

Claims

1. A system for managing network hardware, the system comprising:

memory;

a resource manager comprising a controller coupled to the memory;

the controller of the resource manager being configured to transmit to a first management system and a second management a request for network hardware resource management information;

the controller of the resource manager being configured to receive a reply from the first management system and the second management system identifying the network hardware that are respectively managed by the first management system and the second management system;

the controller of the resource manager is configured to receive and store first rules from the first management system and second rules from the second management system for managing the network hardware;

the controller of the resource manager is configured to determine that the first and second rules respectively from the first management system and the second management system are for managing a same network hardware in which management of the same network hardware is shared between the first management system and the second management system;

the controller of the resource manager is configured to notify the first management system and the second management system that the first management system and the second management system both manage the same network hardware; and

the controller of the resource manager is configured to notify the first management system and the second management system that changes to the same network hardware need to be consulted between the first management system and the second management system.

2. The apparatus of claim 1, wherein the request for network hardware resource management information comprises network hardware management policy information in regard to the network hardware that is managed by a management system.

3. The apparatus of claim 2, wherein the controller initiates communication with the network hardware identified in the reply to the request for network hardware resource management information, wherein the reply includes information regarding physical and logical resources associated with the network hardware.

4. The apparatus of claim 3, wherein the controller is configured to facilitate communication between the first and second management systems that manage the same network hardware.

5. The apparatus of claim 3, wherein the controller is configured to change the operational state of the network hardware when the network hardware is in communication with the controller.

6. The apparatus of claim 5, wherein the network hardware management policy information received from both the first and second management systems for the same network hardware is prioritized according to predetermined criteria, where in the case of competing network hardware management policies, the network hardware management policies of the first management system and the second management system assigned a highest priority supersedes.

7. A method for managing network hardware, the method comprising:

transmitting to a first management system and a second management system a request for network hardware resource management information;

receiving a reply from the first management system and the second management system identifying the network hardware that are respectively managed by the first management system and the second management system, wherein a network management protocol is employed in order to receive and transmit information;

receiving first rules from the first management system and second rules from the second management system for managing the network hardware;

determining that the first and second rules respectively from the first management system and the second management system are for managing a same network hardware in which management of the same network hardware is shared between the first management system and the second management system;

notifying the first management system and the second management system that the first management system and the second management system both manage the same network hardware; and

notifying the first management system and the second management system that changes to the same network hardware need to be consulted between the first management system and the second management system.

8. The method of claim 7, wherein the request for network hardware resource management information comprises network hardware management policy information in regard to the network hardware that is managed by a management system.

9. The method of claim 8, further comprising:

receiving a request to change an operational state of the same network hardware;

determining if the request can be performed based upon an evaluation of the network hardware management policy information that is associated with the same network hardware;

denying the request to change the operational state of the same network hardware in the event that it is determined that conflicting network hardware management polices are associated with the same network hardware; and

granting the request to change the operational state of the same network hardware in the event that it is determined that no conflicting network hardware management policies are associated with the network hardware.

10. The method of claim 9, further comprising facilitating the communication between the first and second management systems.

11. The method of claim 10, wherein the network hardware management policy information received from each of the first management system and the second management system for the same network hardware is prioritized according to predetermined criteria, where in the case of competing network hardware management policies, a network hardware management policy of the first management system and the second management system assigned a highest priority supersedes.

12. The method of claim 11, further comprising enforcing predetermined management system management policy rules that supersede the network hardware management policy information that is associated with the same network hardware.

13. The method of claim 12, further comprising reporting the operational state change of the same network hardware to the first management system and the second management system that are associated with the network hardware.

14. A computer program product that includes a non-transitory computer readable medium useable by a processor, the computer readable medium having stored thereon a sequence of instructions which, when executed by the processor, causes the processor to manage network hardware by:

transmitting to a first management system and a second management a request for network hardware resource management information;

receiving a reply from the first management system and the second management system identifying the network hardware that are respectively managed by the first management system and the second management system, wherein a network management protocol is employed in order to receive and transmit information;

receiving first rules from the first management system and second rules from the second management system for managing the network hardware;

determining that the first and second rules respectively from the first management system and the second management system are for a same network hardware in which management of the same network hardware is shared between the first management system and the second management system;

notifying the first management system and the second management system that the first management system and the second management system both manage the same network hardware; and

notifying the first management system and the second management system that changes to the same network hardware need to be consulted between the first management system and the second management system.

15. The computer program product including the non-transitory computer readable medium of claim 14, wherein the request for network hardware resource management information comprises network hardware management policy information in regard to network hardware that is managed by a management system.

16. The computer program product including the non-transitory computer readable medium of claim 15, wherein the sequence of instructions, when executed by the processor, further causes the processor to manage the network hardware by:

receiving a request to change the operational state of the same network hardware;
