Abstract
Some embodiments of the invention provide a method of remediating anomalies in an SD-WAN implemented by multiple forwarding elements (FEs) located at multiple sites connected by the SD-WAN. The method is performed iteratively. The method receives multiple performance metrics that over a duration of time express a performance of the SD-WAN for at least one particular application associated with flows that traverse the SD-WAN during the time duration. The method uses the received performance metrics to update generated weight values for a topology graph that includes (1) multiple nodes representing the multiple FEs and (2) multiple edges between the multiple nodes representing paths traversed between the FEs by the flows associated with the particular application, said generated weight values associated with said paths. The method uses a topology-based machine-trained process to analyze the topology graph with the generated weight values in order to identify an anomaly in the topology graph that is indicative of an anomaly the SD-WAN for the particular application's traffic flows. For an identified anomaly, the method implements a remedial action to modify the SD-WAN in order to reme…
