Abstract

A method and system for providing QoS in a network after a network failure are disclosed. The network includes at least one primary tunnel and at least one backup tunnel protecting a segment of the primary tunnel. The method includes receiving notification of a failure within the primary tunnel segment and rerouting received packets onto the backup tunnel. The rerouted packets are marked to identify packets affected by the failure and are subject to a different QoS policy than packets that have not been rerouted due to the failure.
