The rapid industry adoption of NETCONF/YANG makes model driven become popular in SDN controller design. However, This is a challenge work to provide a high scaled and high performance model driven architecture to meet the requirement from diversified application. This presentation introduces a YANG Shell mechanism for ONOS based SDN controller, which builds YANG service model handling capability for ONOS while keeps ONOS Core characteristics (e.g. high performance, Scale out) unchanged. It hopefully help rapid APP development for Application developer, and provides YANG based standard interface representation for application to reference.
