Abstract
A method and system for optimizing link aggregation usage during failures is disclosed. The method and system are deployed in a network having a data plane in which data traffic flows between nodes coupled by a link formed by an aggregation of a number of individual connections (e.g., an IMA comprising a plurality of Tor Elines, MPLS transport LSPs, ATM VPCs, etc.) and a control plane for controlling data traffic. The method includes communicating a bandwidth change on the link corresponding to the failure to the control plane. Flapping of the link is deterred. A component of the traffic is released based on a configured policy.
