Abstract

System and method for resource management are disclosed. These include receiving, by a virtualized network function (VNF) manger (VNFM) entity, from a network functions virtualization orchestrator (NFVO) entity a granting indication including a granting granularity in which the NFVO entity permits the VNFM entity to perform multiple VNF management operations for one or more VNFs, determining, by the VNFM entity, that a first VNF management operation is in a scope of permission based on the granting indication upon the first VNF management operation being triggered, and sending, by the VNFM entity, a first resource allocation request for the first VNF management operation to a virtual infrastructure manager (VIM) entity.

Claims

1. A method for resource management comprising:

receiving, by a virtualized network function (VNF) manger (VNFM) entity, from a network functions virtualization orchestrator (NFVO) entity a granting indication including a granting granularity in which the NFVO entity permits the VNFM entity to perform multiple VNF management operations for one or more VNFs;

determining, by the VNFM entity, that a first VNF management operation is in a scope of permission based on the granting indication upon the first VNF management operation being triggered; and

sending, by the VNFM entity, a first resource allocation request for the first VNF management operation to a virtual infrastructure manager (VIM) entity.

2. The method of claim 1, wherein the granting granularity indicates the one or more VNFs permitted to the VNFM entity and the multiple VNF management operations granted for each of the permitted one or more VNFs.

3. The method of claim 2, wherein the one or more VNFs comprises a single VNF, group of VNFs or all VNFs belonging to the VNFM entity.

4. The method of claim 1, wherein the granting indication further comprises a constraint allowed by the NFVO entity for the one or more VNFs.

5. The method of claim 4, wherein the constraint comprises a permitted capacity.

6. The method of claim 5, wherein the method further comprises:

sending, by the VNFM entity, to the NFVO entity a notification message including a consumed capacity during the first VNF management operation.

7. The method of claim 1, wherein the first VNF management operation comprises a VNF lifecycle management (LCM) operation.

8. The method of claim 7, wherein the VNF LCM operation comprises instantiating, scaling, updating, upgrading or terminating operation.

9. The method of claim 1, wherein the method further comprises:

determining, by the VNFM entity, that a second VNF management operation is in the scope of the permission based on the granting indication upon the second VNF management operation being triggered; and

sending, by the VNFM entity, a second resource allocation request for the second VNF management operation to the VIM entity.

10. The method of claim 1, wherein the method further comprises:

determining, by the VNFM entity, that a third VNF management operation is outside the scope of the permission based on the granting indication upon the third VNF management operation being triggered; and

sending, by the VNFM entity, a granting request for the permission of the third VNF management operation to the NFVO entity.

11. A system for resource management comprising:

a memory storage comprising instructions; and

one or more processors in communication with the memory, wherein the one or more processors execute the instructions to;

receive from a network functions virtualization orchestrator (NFVO) entity a granting indication including a granting granularity in which the NFVO entity permits a virtualized network function (VNF) manger (VNFM) entity to perform multiple VNF management operations for one or more VNFs;

determine that a first VNF management operation is in a scope of permission based on the granting indication upon the first VNF management operation being triggered; and

send a first resource allocation request for the first VNF management operation to a virtual infrastructure manager (VIM) entity.

12. The system of claim 11, wherein the granting granularity indicates the one or more VNFs permitted to the VNFM entity and the multiple VNF management operations granted for each of the permitted one or more VNFs.

13. The system of claim 12, wherein the one or more VNFs comprises a single VNF, group of VNFs or all VNFs belonging to the VNFM entity.

14. The system of claim 11, wherein the granting indication further comprises a constraint allowed by the NFVO entity for the one or more VNFs.

15. The system of claim 14, wherein the constraint comprises a permitted capacity.

16. The system of claim 15, wherein the one or more processors further execute the instructions to:

send to the NFVO entity a notification message including a consumed capacity during the first VNF management operation.

17. The system of claim 11, wherein the first VNF management operation comprises a VNF lifecycle management (LCM) operation.

18. The system of claim 17, wherein the VNF LCM operation comprises instantiating, scaling, updating, upgrading or terminating operation.

19. The system of claim 11, wherein the one or more processors further execute the instructions to:

determine that a second VNF management operation is in the scope of the permission based on the granting indication upon the second VNF management operation being triggered; and

send a second resource allocation request for the second VNF management operation to the VIM entity.

20. The system of claim 11, wherein the one or more processors further execute the instructions to:

determine that a third VNF management operation is outside the scope of the permission based on the granting indication upon the third VNF management operation being triggered; and

send a granting request for the permission of the third VNF management operation to the NFVO entity.
