Dynamic quality of service setting system

1. A network device comprising: a processor, an input/output device coupled to the processor, and a memory coupled with the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising:

instantiating at least one quality of service controller, the quality of service controller receiving a request for a change in a quality of service (QOS) setting from a default QOS setting to an altered QOS setting, wherein the request includes a trigger that limits a duration of the altered QOS setting;

analyzing the request to determine if the requested change in QOS setting can be granted;

when the request for a change in QOS setting can be granted, preparing an altered flow rule including a tag identifying the altered QOS setting, wherein the tag includes one or more priority bits created using free bits of an Internet protocol (IP) or a Differentiated Services Code Point (DSCP) address;

using a DSCP bit value in an IP header in conjunction with an IP address converting an 8 bit address to a 48 bit address when changing the default QOS setting to the altered QOS setting; and

pushing the altered flow rule to at least one access hardware.

2. The network device of claim 1 , wherein when granting the request for the altered QOS setting, the quality of service controller identifies a trigger as a limit to the altered QOS setting, when the trigger occurs, quality of service controller reverts to a default flow rule resetting the QOS setting to the default QOS setting.

3. The network device of claim 2 , wherein the trigger includes at least one of a time limit and a session.

4. The network device of claim 1 , wherein the tag includes an altered IP address.

5. The network device of claim 1 , wherein the quality of service controller is instantiated within a software-defined network controller.

6. The network device of claim 1 , wherein the quality of service controller includes an API.

7. The network device of claim 1 , wherein the step of analyzing the request includes determining whether sufficient network elements exist or can be instantiated to provide an altered priority.

8. A system comprising:

a quality of service controller including an input/output device;

at least one user or customer premises equipment (CPE) having a default quality of service (QOS) setting, the at least one user or CPE selectively communicating a request for an altered QOS setting to the quality of service controller, wherein the request includes a trigger that limits a duration of the altered QOS setting;

wherein the quality of service controller, upon determining that the request for the altered QOS setting can be granted, is configured to issue an altered flow rule including a tag establishing the altered QOS setting for the at least one user or CPE, wherein the tag includes one or more priority bits created using free bits of an Internet protocol (IP) or a Differentiated Services Code Point (DSCP) address,

wherein subsequent communications from the user or CPE carry the tag; and

using a DSCP bit value in an IP header in conjunction with an IP address converting an 8 bit address to a 48 bit address when changing the default QOS setting to the altered QOS setting.

9. The system of claim 8 further comprising a software-defined network (SDN) controller, the quality of service controller in communication with the SDN controller, wherein the quality of service controller is configured to query the SDN controller to determine availability of resources supporting the altered QOS setting in response to the request.

10. The system of claim 8 further comprising at least one access hardware, wherein the quality of service controller communicates with the at least one access hardware to deliver the altered flow rule to the at least one access hardware.

11. The system of claim 8 , wherein the request includes a trigger that limits a duration of the altered QOS setting.

12. The system of claim 8 , wherein a trigger identifies at least one of a time limit and a session.

13. The system of claim 8 , wherein the request is a request for a session, and wherein upon expiration of the session, causing the altered QOS setting to change to the default QOS setting.

14. The system of claim 11 , wherein the trigger comprises a maximum time field in an IP address.

15. A method of changing quality of service on demand in a network, the method comprising:

providing a quality of service controller in communication with a software-defined network (SDN) controller and at least one user or customer premises equipment (CPE), where the user or CPE has a default quality of service (QOS) setting;

when a request to change the default QOS setting to an altered QOS setting is received by the quality of service controller from the user or CPE, analyzing whether the request can be granted; and

when granting the request, providing an altered flow rule having a tag that indicates to access hardware that communications from the user or CPE will have the altered QOS setting,

wherein the tag includes one or more priority bits created using free bits of an Internet protocol (IP) or a Differentiated Services Code Point (DSCP) address;

using a DSCP bit value in an IP header in conjunction with an IP address converting an 8 bit address to a 48 bit address when changing the default QOS setting to the altered QOS setting; and

wherein the request includes a trigger that limits a duration of the altered QOS setting.

16. The method of claim 15 further comprising; reverting the altered QOS setting to the default QOS setting upon expiration of at least one of a session and a time limit.

17. The method of claim 15 wherein the SDN controller determines an availability of resources supporting the altered QOS setting in response to the request.

18. The method of claim 15 , wherein a trigger identifies at least one of a time limit and a session.
