Abstract: This disclosure describes techniques for policy validation techniques relating to data traffic routing among network devices. The techniques may include processing a validation request from a controller. A validation request may include information related to a computed path for routing data traffic in a computing network. The processing may include sending one or more path requests to one or more redundant controllers, and comparing computed paths from the redundant controller(s) to the originally computed path. The techniques may include generating a validation response based on comparing the computed paths. In some examples, the techniques may further include determining a health score for the controller. Policy validation techniques may improve data traffic routing among network devices by helping to ensure valid policies are produced.
