Abstract:
1. A method, comprising: 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; wherein the present or pending congestion condition is experienced by a first traffic flow of data packets from the external interfaces of the networking device to the internetworked device; 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; wherein the change in the one or more paths addresses said present or pending congestion condition; wherein the change diverts traffic of one or more other traffic flows of data packets to other paths that are different from the path; wherein the change maintains the path for the first traffic flow of data packets; and changing the one or more paths from the external interfaces to the internetworked system.
