3 NTT Group The largest telecom group in the world* (32 nd in 2013 Fortune Global 500) Regional communication Long distance & international communication, ICT Solutions Application integration Mobile communication Managed ICT Service *In consolidated revenue of billion USD in FY2012 3

4 NTT Communications NTT(Holding Company) Global ICT Solutions with High Quality <Results for FY2012 (ended March 31, 2013)> Financial Result - Operating Revenues: JPY 1,194B (USD 11.9B) - Operating Income: JPY 116B (USD 1.2B) Global Deployment * Employees - NTT Com Group: Approx. 11,000 - NTT Com: Approx. 6,700 - Offices in 39 countries/regions, 102 cities (excluding Japan) - Global Network Service in 196 countries/regions - Global Tier-1 IP backbone provider, one of the largest in Asia - Over 150 data centers, strong increase in Asia/US/Europe * As of February Figures in USD are not official but are provided for reference (exchange rate used is USD 1 : JPY 100) 4

5 Key M&A Achievement Accelerate M&A for providing Global Seamless Services IT Outsourcing Security / Application ICT Solution Hosting / Data Center Network

6 NTT Communications Global IP Network ( GIN ) NTT Communications introduced next-generation IPv6 service and is striving to popularize this service on a global scale. It also served as a core network provider for World IPv6 Day (June 8, 2011), a global 24-hour test of IPv6 deployment that enabled participants to access each other's websites via IPv6 addresses. 6

10 OCN IPv6 : IPv6 Access for Consumers Launched in December 2005 IPv6 Tunneling Service over IPv4 based on L2TP Fixed IPv6 address and non-fixed IPv6 address to be given (two /64 subnet prefixes) Original tunneling software provided for subscribers Radius Mail/Web Proxy IPv6 IPv6 Tunneling Termination Unit IPv4 L2TP,UDP Implemented scarcely used 10

11 Provided IPv6 Accounts by Default OCN provides IPv6 by default for home users since Apr IPv6 has become free of additional charge - IPv6 Prefix is assigned automatically - Users still need 9,000JPY (1,800,000VND) additional cost for dual stack WiFi router NTT FLETS Hikari Next (FTTH) IPv6 IPv6/IPv4 by default IPv6 capable broadband router IPv4 11

12 Ratio of Global IPv6 in Japan (in NTT-NGN) The observed dual stack subscriber ratio has still kept low 100.0% Global IPv6 Ratio on NTT-NGN 90.0% 80.0% 70.0% 60.0% 50.0% 40.0% 30.0% 20.0% 10.0% 0.0% 0.8 % 1.4 % 2.0 % 2.5 % 2.7 % 2012/ / / / / /04 12

13 Why Global IPv6 Could NOT Take Off Additional fee needed Reduce the usage fee and expense Additional Customer contracts with ISP & NTT needed Enabled IPv6 option by default Another BOX required when the customer try to use IPv6 PPPoE 13

14 The Time has Come NTT East/West introduced new version of bundled CPEs ( Home Gateway ) with ISP s IPv6 service function. Most existing bundled CPEs are also planned to be upgraded automatically to support IPv6 PPPoE soon. No more additional box needed, because existing boxes are going to support IPv6 14

16 After You Turn IPv6 ON by Default According to our survey, Even though only a few hyper giants such as Google (incl. YouTube), Facebook, Akamai are IPv6 enabled, they make up most of our traffic ZZ % XX % Streaming Y* Web browsing via dualstack Software Updates via dual stack server YY % 30-50% of traffic by volume will move to IPv6 transport immediately. IP version transition may cause huge traffic shift between upstream providers and peers, when you have IPv6 only free peers or IPv4 only upstreams. 16

17 IPv6 Traffic in GIN That means: 17

18 Avoid Unpredictable Traffic Shift By unified traffic management plan for both IPv4 and IPv6 peering Set dual stack peering as your default choice 18

19 Contribution for IPv6 Development Turning IPv6 On by default may cause unintentional multi-homing How can you setup a small network of devices which have multiple IPv6 upstream without NAT (as usual in IPv4)? RFC7157 shows a possible solution 19

22 NTT Plala s Hikari-TV IPTV Service 2.6M customers use IPv6 CDN 22

23 MAP-E as an IPv6 Application MAP-E is the one of major survival technologies after IPv4 address depletion. We assume IPv6 is the best transport for IPv4! 23

24 Our Reasons to Deploy IPv6 IPv4 has already gone. We still need more IP addresses to provide ubiquitous Internet access for customers To reduce future investment on Carrier Grade NAT devices 24
