1. A method of remediating anomalies in an SD-WAN (software-defined wide-area network) implemented by a plurality of forwarding elements (FEs) located at a plurality of sites connected by the SD-WAN, the method comprising:
determining that a particular anomaly detected in the SD-WAN requires remediation to improve performance for a set of one or more flows traversing through the SD-WAN;
identifying a set of two or more remedial actions for remediating the particular anomaly in the SD-WAN;
for each identified remedial action in the set, selectively implementing the identified remedial action for a subset of the set of flows for a duration of time in order to collect a set of performance metrics associated with SD-WAN performance during the duration of time for which the identified remedial action is implemented;
based on the collected sets of performance metrics, using a machine-trained process to select one of the identified remedial actions as an optimal remedial action in the set to implement for all of the flows in the set of flows; and
implementing the selected remedial action for all of the flows in the set of flows.
