Abstract
In one embodiment, a router in a network reports, a supervisor, capabilities of the router to support fast reroute. The router receives a prediction model from the supervisor that is able to predict failures along a path in the network. The router predicts, using the prediction model, a failure along a primary path in the network that is currently being used by the router to send traffic. The router performs, in advance of the failure predicted by the router, a fast reroute of at least a portion of the traffic from the primary path to a backup path in the network.
