AUTONOMOUS DISTRIBUTED FORWARDING PLANE TRACEABILITY BASED ANOMALY DETECTION IN APPLICATION TRAFFIC FOR HYPER-SCALE SD-WAN

Abstract:

Some embodiments of the invention provide a method for detecting and remediating anomalies in an SD-WAN that includes a controller, an enterprise datacenter, and multiple branch sites each having at least one edge node that includes a set of packet processing stages. At the controller, the method receives from a particular node of a particular branch site a flow notification indicating detection of an anomaly on the particular node. Based on the anomaly, the method dynamically generates trace monitoring rules that specify one or more flows to be traced and provides the trace monitoring rules to the particular node and at least one other node of another branch site. From the particular node and the at least one other node, the method receives trace monitoring results collected in response to the provided trace monitoring rules, and analyzes the results to identify any anomalies and dynamic actions to correct the anomalies.
