  1. Smart Internet R&D and Standardization Taesang Choi, Principal Research GSC-18 Meeting, 22-23 July 2014, Sophia Antipolis, France

  2. SMART Internet InfraR&D Initiative in Korea • S∙M∙A∙R∙T Internet is • SMART Internet is the Value Delivery Platform that implements IT and Network resource virtualization and Fixed-Mobile Converged network using SDN, NFV and Smart Node technologies. • SMART Internet values Open and Standard based Technologies, and focuses on management revolution to provides Best-Fit ICT environment for every application and user. ※ Soft, Manageable, Agile, Robust, and Trustworthy platform 2

  10. VeriSDN : SDN Formal Verification • Two Verification Modes • Runtime symbolic verification • Off-line symbolic verification Applications (Python, Java, C, Ruby, etc.) 1. Execution (SDN Controller) Static Checking Applications (Python, Java, C, Ruby, etc.) Model Checking 2. Formal Verification 1. Execution (SDN Control Emulator) Theorem Proving ….. Static Checking Model Checking 2. Formal Verification SDN Data plane (heterogeneous devices, switches, etc.) Theorem Proving ….. Off-line symbolic verification Runtime symbolic verification Verified Applications 10

  11. TTA PG220 Activities • TTA PG220 (Future Internet Project Group) • Develop standards for Smart Internet • Participants: ETRI, KT, SKT, LGU+, Ubiquoss, Dasan networks, etc. SDN/Smart Internet Virtual network (Application/Service) App-N Smart Broadcast App-Y Smart Home (5) SDN programming API Smart Work App-X Network/Service Controller (4) Network controller CSB-SDN Interface (3) SNP Service Interface Smart Node Platform (Smart Internet S/Wplatform) SNP NFV SDN switch (2) SNP SystemInterface Smart Node Smart Node Tera-gradeplatform NFV-enabled L4-L7 Appliance NFB platform (1) Common H/WPlatform (Tera-grade) .....

  12. TTAPG220 Standards (1/2) • Common hardware platform NFB common platform Tera-gradeplatform NFV-enabled L4-L7 Appliance 12

  13. TTAPG220 Standards (2/2) • Common software platform 13

  14. 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

  15. 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

  16. 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
