This presentation will describe SDN-based use cases that are now deployed or in planning. The Science DMZ compatible use cases are Volumetric Attack Mitigation, Firewall Bypass, Elephant Flow Management, closed loop event/threat management solutions and Network Visibility. We will also discuss how SDN can assist in delivering Digital Learning-based Lesson plans. CERN openlab and other REN operators are planning or considering near-term deployments. Mr Beckmann will also provide a status update on OpenFlow and Next Gen SDN efforts (mainly P4).
