METHOD AND SYSTEM OF PROVIDING QUALITY OF EXPERIENCE VISIBILITY IN AN SD-WAN
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.
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.
