Two recent developments

MAEMURA Akinori, June 16, 2011 3

KDDI announced IPv6 provision

• Monday April 18 – just after APNIC’s runout • effective immediately• on its FTTH solution “au Hikari （光）” • No additional fee, no customer action needed

NTT’s FLETS Hikari starts IPv6 Internet access

• NTT’S FLETS connects ISP and end-user residences

• FLETS Hikari （光） Next == NTT’s NGN offer• After years

consideration• Multiple ISPs have

already announcethe adoption

Observation from Operators being successful

MAEMURA Akinori, June 16, 2011 6

IPv6, standardized in 1995,

• And assumed to be deployed gradually replacing IPv4 by the exhaustion of it

• But it never happened until now

Assumption Actual

Why not?

• No compatibility with IPv4

• No direct merit for users

• Significant cost

IPv4 Internet

Growth of the Internet

Growth of the Internet

Which is reasonable way to go?

Network Externalitysays IPv4

IPv6 Internet

Exhaustion ofIPv4 Address

Internet with few services and few eyeballs

Internet with full of services and eyeballs

At least until the exaustion

MAEMURA Akinori, June 16, 2011 9

Dilemma of Operators and solution for it

• Definitely needs IPv6 for Future Internet– to accommodate more services and eyeballs

• Significant Cost for no direct merit for customers

• Need a miracle?• Need Government fund?

• A solution: long, steady, low-key and patient endeavors make it happen

MAEMURA Akinori, June 16, 2011 10

Operators being successful has been taking long, low-key and patient efforts

• Time is money – Plan and action over years will benefit in many aspects:– Many small investments are easier to be

justified than few big investments– IPv6 enabled equipment to renew on

depreciation– Firmware upgrade when IPv6 enabled version

got available reasonably– Play with lab network and learn about IPv6 to

gain the expertise: literacy reduces the cost

MAEMURA Akinori, June 16, 2011 11

There has been no miracle…

• Task Force on IPv4 Address Exhaustion, Japan– three years since 2008– actions to multi-stakeholders– Information – action plan template, training, reference

network design, status update

• NTT FLETS is at last being ready– Most ISPs can use it for their IPv6 access from

residences

• Operators has been taking patient efforts– Bottom up, low-key, long and steady– Gradually prepare for IPv6, in order to save the

customers from the crisis
