The present method for advanced fail-over packet label swapping for a
packet network having a working path and a protection path, each of the
working path and protection path interconnected by a near-end switch and
a far-end switch includes: provisioning the working path, protection
path, near-end switch, and far-end switch with a failure counter delay;
monitoring heartbeat packets on one of the near-end switch and the
far-end switch during a monitoring period to determine a number of
packets that were not received by at least one of the switches during the
monitoring period; determining if the determined number of packets
exceeds a predetermined lost packet value for the failure counter delay;
and responsive to the determined number of packets exceeding the
predetermined lost packet value, delaying the monitoring for a period of
time equal to the failure counter delay.
