Abstract

In one aspect, a computerized method useful for providing quality of experience visibility in a software-defined networking in a wide area network (SD-WAN) includes the step of providing a path state machine. With the path state machine, the method establishes a set of flags configured to determine a path eligibility that meets a specified scheduling criteria for a path selection condition. The method provides a link state machine. With the link state machine, the method establishes another set of flags configured to determine a link eligibility that meets a scheduling criteria for an event reporting parameter.

Claims

1. A computerized method useful for providing quality of experience visibility in a software-defined networking in a wide area network (SD-WAN) comprising:

providing a path state machine;

with the path state machine, establishing a set of flags configured to determine a path eligibility that meets a specified scheduling criteria for a path selection condition;

providing a link state machine;

with the link state machine, establishing another set of flags configured to determine a link eligibility that meets a scheduling criteria for an event reporting parameter.

2. The computerized method of claim 1 further, wherein the link state machine determines that the path selection conditions are met before setting and clearing a flag.

3. The computerized method of claim 2, wherein a network event is generated when the flag is set or cleared.

4. The computerized method of claim 3, wherein an orchestrator displays a summary chart of a quality of a link as measured by the link state machine.

5. The computerized method of claim 4, wherein the orchestrator displays a summary chart of a quality of the link as measured for a set of target metrics.

6. The computerized method of claim 5, wherein a voice data network traffic, a video data network traffic, a transactional data network traffic or a bulk data network traffic are measured separately.

7. The computerized method of claim 6 further comprising:

generating a quality score based on the target metrics and quality measurements.

8. The computerized method of claim 1, wherein the path state machine comprises a finite state machine that runs periodically to monitor and update a state of set of paths between a set of network endpoints in the wide area network.

9. The computerized method of claim 2, wherein the link state machine comprises another finite state machine that runs periodically to monitor and update the state of links in the wide area network.

10. The computerized method of claim 3, wherein a link comprises a collection of paths to a remote network endpoint that originates from a common network source.

11. A computer system useful for providing quality of experience visibility in a software-defined networking in a wide area network (SD-WAN) comprising:

at least one processor configured to execute instructions;

a memory containing instructions when executed on the processor, causes the at least one processor to perform operations that;

provide a path state machine;

with the path state machine, establish a set of flags configured to determine a path eligibility that meets a specified scheduling criteria for a path selection parameter;

provide a link state machine;

with the link state machine, establish another set of flags configured to determine a link eligibility that meets a scheduling criteria for an event reporting parameter.

12. The computer system of claim 11, wherein the path state machine comprises a finite state machine that runs periodically to monitor and update a state of set of paths between a set of network endpoints in the wide area network.

13. The computer system of claim 11, wherein the link state machine comprises another finite state machine that runs periodically to monitor and update the state of links in the wide area network.

14. The computer system of claim 11, wherein a link comprises a collection of paths to a remote network endpoint that originates from a common network source.
