Predict Boldly, Recover Cautiously: Fast On-Router Route Anomaly Prediction and Recovery

Route anomalies can quickly propagate into path detours, packet loss, and service degradation. However, existing pipelines are often centralized: routers export telemetry to a controller, the controller performs data cleaning and diagnosis, and mitigation actions are then pushed back to the network. This observe-then-r...
