Abstract
Embodiments of the disclosure are directed to tunnel flap damping in a traffic engineered network. One exemplary method for tracking a re-routing history of Multi-Protocol Label Switching (“MPLS”)/Generalized MPLS (“GMPLS”) tunnels over intervals includes measuring a number of policy-based re-routes during at least one measurement interval; determining a tunnel re-route frequency based on the measurement; comparing the tunnel re-route frequency to a frequency threshold; and determining if the tunnel re-route frequency exceeds the frequency threshold and, if the tunnel re-route frequency exceeds the frequency threshold, delaying at least one tunnel re-route.
