As the prevailing technique of Software-Defined Networking (SDN), OpenFlow introduces significant programmability, granularity and flexibility for many network applications to effectively manage and process network flows. However, OpenFlow only provides a simple "match-action" paradigm and lacks the function of stateful forwarding for SDN data plane, which limits it to support advanced network applications. Heavily relying on SDN controllers for all state maintenance incurs both scalability and… CONTINUE READING
