Abstract

Claims (52)

1. A method for capacity licensing for software comprising a plurality of features, the method comprising:

receiving a capability request from a client device at a license server, the capability request indicating a license, a set of client-reported license rights, and capability information for the client device;

executing instructions stored in a memory in the license server, wherein execution of the instructions by a processor:

identifies a deduction record associated with the client device, the deduction record including a plurality of license rights, each license right associated with a different feature of the software, wherein different capability information for another client device results in a different deduction record with a different set of license rights,

determines whether there is a mismatch between the set of client-reported license rights and a set of client device's license rights in the identified deduction record, wherein a mismatch leads to issuing a capability response to correct an error in the deduction report, and wherein a match between the set of client-reported license rights and the set of the client device's license rights in the identified deduction record is followed by determining whether there is a change in the set of client device's license rights at the license server:

and

if there is a change in the set of client device's license rights,

selecting a new set of license rights for the client device from the plurality of available license rights associated with the license, the selection of the new set of license rights based on the capability information for the client device,

sending a capability response to the client device, the capability response comprising the selected new set of license rights only, wherein subsequent exercise of the license by the client device is governed by the selected new set of license rights and features of the software associated with the selected new set of license rights, and

updating the deduction record in memory, the deduction record reflecting that the selected new set of license rights has been provided to the client device from a license pool, wherein an information response to an information request acknowledges the stored deduction record; and

if there is no change in the client device's license rights, renewing the set of the client device's license rights by extending the expiration time by a previously defined borrow interval included in a capability response sent to the client device.

2. The method of claim 1 , wherein the capability request comprises a host identifier, a timestamp, rights identifiers, and vendor data.

3. The method of claim 1 , wherein the information request comprises a host identifier, a timestamp, rights identifiers, and vendor data.

4. The method of claim 1 , wherein the acknowledgement further comprises an acknowledgement of receipt of the information request.

5. The method of claim 1 , wherein the requesting client device transmits the information request to each server from a server list stored in memory.

6. The method of claim 1 , wherein each server from a server list transmits an information response to the requesting client device, each server storing a deduction record.

7. The method of claim 1 , wherein the license pool comprises licenses available for allocation.

8. The method of claim 1 , wherein the license server identifies the serving of license rights further based on a license policy.

9. The method of claim 1 , wherein the identification of the selected new set of license rights occurs dynamically.

10. A system for capacity licensing for software comprising a plurality of features, the system comprising:

one or more embedded systems having one or more client devices in communication with a license server; and

the license server having a license pool, wherein the license server:

receives a capability request from one of the client devices, the capability request indicating a license, a set of client-reported license rights, and capability information for the requesting client device;

executes instructions stored in a memory, wherein execution of the instructions by a processor:

identifies a deduction record associated with the client device, the deduction record including a plurality of license rights, each license right associated with a different feature of the software, wherein different capability information for another client device results in a different deduction record with a different set of license rights,

determines whether there is a mismatch between the set of client-reported license rights and a set of the client device's license rights in the identified deduction record for the client device, wherein a mismatch leads to issuing a capability response to correct an error in the deduction report, and wherein a match between the set of client-reported license rights and the set of the client device's license rights in the identified deduction record is followed by determining whether there is a change in the set of client device's license rights in the license server,

and

if there is a change in the set of client device's license rights,

selecting a new set of license rights for the requesting client device from the plurality of available license rights associated with the license, the selection of the new set of license rights based on the capability information for the requesting client device;

sending a capability response to the requesting client device, the capability response comprising the selected new set of license rights only, wherein subsequent exercise of the license by the requesting client device is governed by the selected new set of license rights and features of the software associated with the selected new set of license rights; and

updating the deduction record, the deduction record reflecting that the selected new set of license rights has been provided to the requesting client device from the license pool, wherein an information response to an information request acknowledges the deduction record; and

if there is no change in the client device's license rights, renewing the set of the client device's license rights by extending the expiration time by a previously defined borrow interval included in a capability response sent to the client device.

11. The system of claim 10 , wherein the capability request comprises a host identifier, a timestamp, rights identifiers, and vendor data.

12. The system of claim 10 , wherein the information request comprises a host identifier, a timestamp, rights identifiers, and vendor data.

13. The system of claim 10 , wherein the acknowledgement further comprises an acknowledgement of receipt of the information request.

14. The system of claim 10 , wherein the information request is transmitted to each server from a server list.

15. The system of claim 10 , wherein each server from a server list transmits the information response to the requesting client device, each server storing a deduction record.

16. The system of claim 10 , wherein the license server comprises a primary controller and a secondary controller.

17. The system of claim 10 , wherein the requesting client device is a virtual appliance.

18. The system of claim 10 , wherein the license server identifies the selected new set of license rights further based on a license policy.

19. The system of claim 10 , wherein the identification of the selected new set of license rights occurs dynamically.

20. The system of claim 10 , wherein the license server comprises a database for storing device license reservations.

21. A non-transitory computer-readable storage medium, having embodied thereon a program executable by a processor to perform a method for capacity licensing for software comprising a plurality of features, the method comprising:

receiving a capability request from a client device at a license server, the capability request indicating a license, a set of client-reported license rights, and capability information for the client device;

executing instructions stored in memory in the license server, wherein execution of the instructions by a processor:

identifies a deduction record associated with the client device, the deduction record including a plurality of license rights, each license right associated with a different feature of the software, wherein different capability information for another client device results in a different deduction record with a different set of license rights,

determines whether there is a mismatch between the set of client-reported license rights and a set of client device's license rights in the identified deduction record, wherein a mismatch leads to issuing a capability response to correct an error in the deduction report, and wherein a match between the set of client-reported license rights and the set of the client device's license rights in the identified deduction record is followed by determining whether there is a change in the set of client device's license rights at the license server, and

if there is a change in the set of client device's license rights,

selecting a new set of license rights for the client device from the plurality of available license rights associated with the license, the selection of the new set of license rights based on the capability information for the client device,

sending a capability response to the client device, the capability response comprising the selected new set of license rights only, wherein subsequent exercise of the license by the client device is governed by the selected new set of license rights and features of the software associated with the selected new set of license rights, and

updating the deduction record in memory, the deduction record reflecting that the selected new set of license rights has been provided to the client device from a license pool, wherein an information response to an information request acknowledges the stored deduction record; and

if there is no change in the client device's license rights, renewing the set of the client device's license rights by extending the expiration time by a previously defined borrow interval included in a capability response sent to the client device.
