Automatic fast failure restoration on software-defined optical switch controller with NETCONF/RESTCONF for all-photonics network

For rapid service creation, software-defined network (SDN) controller is promising when establishing access networks on the all-photonics (APN). To our knowledge, no study has investigated fast restoration from SDN controllers with NETCONF/RESTCONF for high-reliability requirements. This paper proposes an automatic failure application a optical switch NETCONF/RESTCONF. It includes periodic device information collection and detection power via controller. Evaluations show that achieves 0.9-s in system uses server
