Abstract

A specification of an intent that identifies a desired service and a reference architecture is received. The desired service is rendered to provide instructions for dispatch to a plurality of devices having roles. Rendering the desired service includes invoking a service rendering program function based on the reference architecture and a role of a specific device. A new reference architecture may be implemented by specifying a new service rendering program function for the new reference architecture.

Claims

1. A method of configuring system resources including:

receiving a specification of an intent that identifies a desired service and a reference architecture; and

using a processor to render the desired service to provide instructions for dispatch to a plurality of devices having roles;

wherein rendering the desired service includes invoking a service rendering program function based on the reference architecture and a role of a specific device; and

wherein a new reference architecture may be implemented by specifying a new service rendering program function for the new reference architecture.

2. The method of claim 1, wherein the intent identifies declarative requirements of the desired service.

3. The method of claim 1, wherein the desired service includes a network service.

4. The method of claim 1, wherein the plurality of devices includes a plurality of nodes of is the reference architecture.

5. The method of claim 1, wherein the plurality of devices includes a network switch device.

6. The method of claim 1, wherein the reference architecture identifies a network topology to be utilized to provide the desired service.

7. The method of claim 1, wherein the reference architecture identifies a protocol to be utilized to provide the desired service.

8. The method of claim 1, wherein the desired service may be rendered using at least one of a plurality of different reference architectures.

9. The method of claim 1, wherein the service rendering program function generates declarative requirements to be provided to the specific device.

10. The method of claim 1, wherein the reference architecture identifies an L3 Clos network architecture.

11. The method of claim 1, wherein the roles include roles within the reference architecture.

12. The method of claim 1, wherein rendering the desired service includes identifying a different service rendering program function for each different role of the plurality of devices.

13. The method of claim 1, wherein invoking the service rendering program function includes providing to the service rendering program function a blueprint of the intent and an identifier of the specific device.

14. The method of claim 1, wherein rendering the desired service includes using a dispatcher that identifies and invokes a function instance for each of the devices to be utilized to provide the desired service.

15. The method of claim 1, wherein rendering the desired service includes invoking a verification model program function based on the reference architecture and the role of the specific device.

16. The method of claim 15, wherein the verification model program function generates a verification model for the specific device.

17. The method of claim 16, wherein the verification model identifies one or more parameters to be monitored for the specific device.

18. The method of claim 16, wherein the verification model is provided to the specific is device.

19. A system of configuring system resources, comprising:

a processor configured to;

receive a specification of an intent that identifies a desired service and a reference architecture; and

render the desired service to provide instructions for dispatch to a plurality of devices having roles;

wherein rendering the desired service includes invoking a service rendering program function based on the reference architecture and a role of a specific device; and

wherein a new reference architecture may be implemented by specifying a new service rendering program function for the new reference architecture; and

a memory coupled to the processor and configured to provide the processor with instructions.

20. A computer program product for configuring system resources, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving a specification of an intent that identifies a desired service and a reference architecture; and

rendering the desired service to provide instructions for dispatch to a plurality of devices having roles;

wherein rendering the desired service includes invoking a service rendering program function based on the reference architecture and a role of a specific device; and

wherein a new reference architecture may be implemented by specifying a new service rendering program function for the new reference architecture.
