Abstract: Systems and methods provide for route optimization using real time traffic feedback. A network management system can subscribe to receive streaming telemetry (e.g., at line rate) for traffic associated with one or more managed network entities (e.g., flows, sites, networks, network devices, endpoints, applications, etc.) selected for route optimization. The network management system can determine a set of possible routes for the traffic. The network management system can compute metrics (e.g., packet loss, bit rate, throughput, delay, availability, jitter, etc.) for a set of possible routes for the traffic based on the streaming telemetry. The network management system can determine an optimal route from the set of possible routes based on the metrics. The network management system can inject the optimal route into the one or more network devices receiving the traffic to override a native route (e.g., determined by a routing protocol executed by the network devices).
