Abstract
An example method includes receiving, by an SD-WAN system, WAN link characterization data for a plurality of WAN links of the SD-WAN system over a time period; and for each site of a plurality of sites of the SD-WAN system, generating, by the SD-WAN system, a local policy for the site, wherein generating the local policy is based on a machine learning model trained with the WAN link characterization data for the plurality of WAN links, and providing the local policy to an SD-WAN edge device of the site.
Claims20
Non-transitory computer-readable storage media comprising instructions that, when executed, configure processing circuitry of a computing system to:
- receive wide area network (WAN) link characterization data for a plurality of WAN links of a software-defined WAN (SD-WAN) system over a time period;
- and
- for each site of a plurality of sites of the SD-WAN system,
- generate a local policy for the site based on a global policy comprising one or more rules and applicable to all of the plurality of sites and a machine learning model trained with the WAN link characterization data for the plurality of WAN links, and
- provide the local policy to an SD-WAN edge device of the site.
A software-defined wide area network (SD-WAN) system comprising processing circuitry in communication with memory and configured to:
- receive WAN link characterization data for a plurality of WAN links of the SD-WAN system over a time period, and
- for each site of a plurality of sites of the SD-WAN system,
- generate a local policy for the site based on a global policy comprising one or more rules and applicable to all of the plurality of sites and a machine learning model trained with the WAN link characterization data for the plurality of WAN links, and
- provide the local policy to an SD-WAN edge device of the site.
Non-transitory computer-readable storage media comprising instructions that, when executed, configure processing circuitry of a software-defined wide area network (SD-WAN) edge device to:
- receive, from a network analysis system, a machine learning model trained with WAN link characterization data for a plurality of WAN links of a plurality of sites;
- generate a local policy for the SD-WAN edge device based on the machine learning model;
- and
- assign, based on the local policy, a service or application of the SD-WAN edge device to a WAN link of a plurality of WAN links associated with the SD-WAN edge device.
