Why IPv6?
Many technical advantages– No more NAT– P2P, IPSec– Plug and Play
Limitation of IPv4– Routing table– Address shortage
New applications & new business opportunitiesHow IPv6 can change the world?

Limitation of IPv4
Nobody could predict the current scale of the Internet when TCP/IP was designed.
Address Scarcity Global routing table size

How soon will 2009 be?
We need experiences for new technology well in advance.– Transition takes time
Address Scarcity increases operation cost and other costs– Complicated network design
• NAT/private address• Insufficient global address assigned
– Complicated procedure for address allocation and assignment

Cost?
Transition cost from IPv4 to IPv6? Cost for keeping IPv4?
– Operation cost– R&D cost for NAT, etc.

Transition cost
It’s like energy level transition in chemical reactions.

Global Routing Table Size Currently, 110k Increasing every year,
every month… Size affects routing
convergence time and eventually stability of the Internet
Router performance is being improved greatly…
Catastrophic accidents occurred in the past.

IPv6’s Merit? (again)
IPv6 is not functionally different in principle, but practically different– “Quantity” changes “quality”
• Only by sufficiency of addresses, every equipment can be assigned a global address and be accessible from the world.
– Built-in IP-sec encourages its use, but not separate IP-sec module does.

Extending the Internet…
NAT+Private Addresses to all Global Addresses– Some applications don’t work in NAT+private enviro
nments• NetMeeting, Napstar, VoIP…
Computers to non-Computers– In office
• Phone, FAX, desk, clock, camera, coffee server, meeting room…
– At home• Home appliance, car, front door, bath, …

Example of Home Appliance (I)
HA utilizes contents from the network HA is upgraded from the network.
– Like a COMPUTER
HA will grow according to user’s preference

Ex) Growing to be a microwave specialized in Chinese cuisines !

Example of Home Appliances (II)
utilize information which would be otherwise discarded
・ frequency/time the oven function is used・ healthiness of power unit
・ frequency/time of door opened・ contents inside

Example of Automobile Famous example: generating fine-grained weather information
– GPS -> location– r.p.m. -> speed of the car– Movement of wiper -> precipitation
Information Retrieval on demand– Congestion info– Restaurant info on demand

IPv6 and Mobile Terminal
Personal interface to the IPv6 network– AAA– Various use
• Information retrieval
• Control HA from remote
• E-commerce
• VoIP (Voice over IP, Video over IP)

IPv6 = Information Exchange Platform
IPv6 will grow to be a platform for Information Exchange– Win-Win situation for all
• Sell information to those who need this for their business• Pay money to users who give their information
– Information exchanges occur not only between home electronic vendors and their users, but among heterogeneous industry sectors, home users and equipments, various sensors in public, etc.
– Authentication & authorization and privacy protection mechanism should be included in the platform.
A lot of opportunities for new applications and your business!

IPv6 in Enterprise Network
Combination of firewall model and IPSec model would give more powerful solutions to enterprise networks.

Thinking more objectively…
All these merits are just possibilities which nobody has proved.
Believe or not? Try or just watch(do nothing)? It’s up to you!
But we should know– a few business chances in what has already been proved.– Experiences are essential for any next step
2002© Takashi Arano
Perspective of 2002 Windows XP will let people feel IPv6 near at hand More real IPv6 applications emerging More commercial activities in Japan, and maybe in Asia
and Europe as well More constructive and practical discussion will be
progressed, although some criticism will be shown– More collaborative discussion among R&D, operations, business
sectors are expected.
Collaboration among various countries in Asia, Europe and US.
Let’s go ahead together!
