3. Japanese Internet in 2011 • Number of fixed broadband subscribers are 20 million and increasing. But increasing ratio is gradually down. • Global IPv4 address has been run out, and IPv6 Internet access service is about to launch. • Smart phone users are rapidly increasing, and LTE service is already available since Dec. 2010.
4. Japanese Internet
5. JPNAP • 10 years old • 4 footprints in JAPAN • ~100 x 10GE, 60 x 1GE • 250Gbps+ in Total
6. JPNAP • jpnap-all-longlong.png
7. Back in 2004 • 30Gbps+ • ~50 customers • Large ISPs started using 10GE • Annoying traffic congestion • New technologies were getting mature
8. What the Japanese Internet looked like in 2004 Transit 2

9. Still Good Old Days? • Game! • MMORPG hosted in North Asia (Korea, China, ...) • TE was the most important for QoE • p2p • Transit price going downhill • Since Cogent hit the market
10. New Technologies
11. More Focus on Applications
12. Hyper Giants were already big enough (2008) Transit 2

13. • Anomaly traffic was a headache • Flow based Analysis More focus on applications
14. Japanese authorities permitted providers to limit huge customer traffic (like p2p) in some cases for network neutrality More focus on applications
15. Today
16. In case that access networks become oligopoly Transit 2

17. Possible future trends
18. How do we get along with
19. Possible scenario? • Changing role of IX • IX in Japan will be an aggregator of content providers and application service providers, and connect to access providers
20. Aggregating contents providers Transit 2

22. Possible scenario? • IXes in Japan will be merged • JPIX and JPNAP as one?? • Commercial competition ends • Merged and transferred to non- profit organization??
23. Asia •  Asian countries will become much more closely related than before •  Materials, designing, manufacturing, delivery, … and market is expanding as well •  Supply-chain is supported by communications •  On the other hand, communication on the Internet in Asian countries is smaller than expected •  More than tens of gigabit traffic in IX are in Japan, Hong Kong, Korea, and India •  We can see a lot of room to growth in other Asian countries
24. IX Ring in Asia •  ISPs in Asia should be a lplatformz for communication in this region, which accelerates economical growth in Asia •  Their peering should not be restricted by a few transit providers. IX and layer 2 connection among them possibly support it Next step •  Global Ring? •  Or alliances and competition between IXes?
25. What is Internet Exchange? •  IX is inherently lLayer-2 networkz and lconnecting ASesz •  Already we are in the age of not lexchange POINTz but lexchange PLANEz •  Combination of IX and L2 network will expand •  Not only in a city or country but regionally or globally •  Layer 2 network: Keyword is lvirtualizationz •  L2 pseudo-wire can be provided over various network infrastructures. •  Increasing lflexibilityz of our services
