1. A method comprising:
obtaining, by a device, an indication of a network event predicted by a routing engine for a network, wherein the routing engine is configured to reroute, based on the network event, traffic along one or more network paths associated with the network event;
initiating, by the device, monitoring of the one or more network paths associated with the network event, to determine one or more states of the network;
making, by the device, a comparison between the one or more states of the network and a set of one or more constraints;
determining, by the device, that the network event predicted by the routing engine is incorrect based on the comparison; and
in response to determining that the network event predicted by the routing engine is incorrect, providing, by the device, a prediction cancellation notification to the routing engine that instructs the routing engine that the network event predicted by the routing engine is incorrect, causing the routing engine to prevent the traffic along the one or more network paths associated with the network event from being rerouted based on the network event.
