Abstract
Techniques are provided for updating best path based on real-time congestion feedback. A method comprises monitoring packets received from an internetworked system, wherein the packets are received on one of a plurality of external interfaces of a networking device; detecting that a received packet includes real-time information that signals a present or pending congestion condition on a path from the external interfaces of the networking device to the internetworked system; notifying a control logic of the real-time information; receiving from the control logic control information defining a change in one or more paths from the external interfaces to the internetworked system; and changing the one or more paths from the external interfaces to the internetworked system. Examining ingress traffic on external interfaces of an internetworked system can cause changes to routes, routing policies and PBRs in routers of the first internetworked system in response to real-time congestion.
