STRATEGIC DIRECTION • SDN and NFV standardization is under progress in parallel. Global coordination among two groups is required • SDN/NFV standardization in software platform and relevant interfaces are actively in progress but that of hardware platform is relatively in active. For open hardware platform standardization requires attention • Transport SDN seems a common interest as a high priority item among fixed or wireless carriers. Faster standardization efforts may help the relevant industry • Standardization of SDN South/North-bound APIs are under active progress but East-West interface needs coordination as well GSC-18, 22-23 July 2014, Sophia Antipolis
CHALLENGES & HOT ISSUES • Autonomic management and control (AMC) are also attracting attentions for cloud data center management and M2M/IoT infrastructure management. Efforts to combine AMC with SDN/NFV in terms of standardization are also worth of global standardization collaboration • NFV introduces many virtual middleboxes and service chaining is one aspect of managing them but more comprehensive management framework and its standardization are needed for widely distributed middleboxes GSC-18, 22-23 July 2014, Sophia Antipolis
NEXT STEPS / ACTIONS • Possible standardization items for collaboration • T-SDN • SDN Scalability and Reliability Architecture • SDN East-West Interface • Autonomic Management and Control • Co-work among GSC members including various SDO activities such as ITU-T SG13/SG15, IETF, and ONF GSC-18, 22-23 July 2014, Sophia Antipolis
