1 R&D on Future Internet in Asia Dagstuhl Seminar on Architecture and Design of the Future Internet ~17 Sue Moon

2 Future Internet Imperatives in Asia Future Internet for the other billions Internet research benefits came in 30 to 40 years More than half of FI users will be in Asia Time to invest AsiaFI Led by Kilnam Chon, Jun Murai, Jun Bi

3 3 Future Internet Projects in Korea FI Key Technology Research by Yanghee Choi since 2007 IITA Robust Mobility Management CASFI (Collect, Analyze, and Share for Future Internet): High-Precision Measurement and Analysis Research Next Generation Network ITRC (Jongkwon Kim) Future Internet Modelling (Junghan Kim) Interdisciplinary ETRI Virtualized Platform Testbeds (KOREN, KREONET) Industry (Samsung)

4 Femtocell-based Wireless Testbed A general testbed for WCDMA networks Virtualization of base and mobile stations Remote configuration and experiment 4

5 KAIST Mesh Testbed: Common Code for Future Internet New L2 New L3 New L4 New L7 L4 L7 KERNEL Driver Interface B MA C MBMAMB A Basic Stack (Linux) Overlay Stack (GlomoSim) Flow B (ex: DHCP) Flow A (ex: OLSR) Flow C (ex: HTTP) Flow A (ex: Overlay MAC) Real Experimentations with Simulation Codes KAIST Mesh Network 5

6 Optical Path in the Core Network : Light Trail A generalization of light-paths, such that multiple nodes along a trail can participate in time differentiated communication over the same established trail – increased link utilization o-grooming, e-grooming Distributed LT algorithm is proposed Verified by simulation Light path Super frame Transport for Optical Core 6

7 Delay/Disruption Tolerant Networking : Hierarchical Spreading DTN Routing Epidemic Spread & Wait Hierarchical Spreading is proposed 7

8 Internet Sibilla Distributed applications are popular in todays Internet. » Peer-to-peer file sharing, CDNs, multi- player online games These applications benefit from the information about the network-internal performance characteristics. » Nearest neighbor discovery, Super peer selection, Distribution tree construction »DNS-like system, where applications Send real-time performance queries and Receive information on desired metrics Without doing measurements by themselves 8

9 Network Engineering-enabled Mesh Network Per-aggregation Queueing Scheduling among backhaul links Flow control at edge router local backlog source rateutility func differential backlog 9

10 CODI Y X Manager of Content ID A Regional Root with Data A Content ID of A Low- tier Hash (A) = 2 High- tier Content Delivery Infrastructure (CODI) Two-tier Name Resolution for Content Oriented Networking low-tier : tree (per ISP) High-tier : DHT (distributed) Better performance than DHT, Tree (DONA) ISP friendly

11 DACON: Decentralized and Autonomous Content Overlay Network Overlay network for content search and delivery is formed by user assistance Incremental content search Incentive systems for AP providers : free access by users WiFi based 11

12 Dynamic Service Composition Service-oriented Architecture Generalized service components Networking and computing service are also components Service broker for service discovery, composition and management 12

13 National Testbeds KREONET KOREN

14 KOREN international links

15 Future Internet Forum Established in 2006 to promote R&D collaborations in Future networking Building research communities Workshops, seminars, publications Research Council General guidelines, technical documents Working groups Architecture Wireless Service Testbed Policy 15

16 16 Forum Events International Conferences (annual) Internet of the Future, July 20-22, 2006, Seoul, Korea International Future Internet Workshop 2007, July 9-10, 2007, Seoul National University CFI 2008, June 18-20, Seoul, Korea CFI 2009, June 17-19, 2009 Future Internet Camp (twice a year) 2007 Aug , Jeju Island 2008 Feb , 2008, Seoul National University (with AsiaFI school) Aug , Jeju Island ( with AsiaFI school) 2009 Feb , SNU Aug , Jeju

17 17 FIF Recommendations Long-term national initiatives Selection & concentration Open to interdisciplinary research Global cooperation CJK, Europe, USA, Africa, India

18 JAPAN: CORE Collaborative Overlay Research Environment Overview Private PlanetLab based testbed Overlay over JGN2, WIDE, SINET 52 nodes at 10 sites Future Directions Wireless/sensor/optical networking PlanetLab federation
