Abstract
A network controller comprising a processor configured to obtain topology information of a network, wherein the topology information indicates a plurality of non-software-defined networking (non-SDN) network elements (NEs) interconnected by a plurality of links in the network, analyze each non-SDN NE according to the topology information to determine whether the non-SDN NE is a candidate NE for establishing a backup tunnel to protect a single-link failure at one of the plurality of links, and select a plurality of target NEs from the candidate NEs to protect against all single link-failures in the network, and a transmitter coupled to the processor and configured to send a first message to a first of the target NEs to dynamically enable software-defined networking (SDN) functionalities at the first target NE in order to facilitate single-link failure protection in the network.
