What is IPV6?
 目前分配給電腦的位址稱為IPv4位址,位址長
度為32位元，其位址格式為210.130.1.1.
 而IPv6位址長度為128位元( 3.4*10^38 IP
Addresses) ，其位址格式與IPv4位址不同
 Ex:
3ffe:0102:0000:0000:0000:0000:0000:0000

IPv6 features
The following are the features of the IPv6 protocol:
 New header format
 Large address space
 Efficient and hierarchical addressing and routing
infrastructure
 Stateless and stateful address configuration
 Built-in security
 Better support for quality of service (QoS)
 New protocol for neighboring node interaction
 Extensibility

Why IPv6?
 Many technical advantages
– No more NAT
– P2P, IPSec
– Plug and Play
 Limitation of IPv4
– Routing table
– Address shortage
 New applications & new business opportunities
Cost?
 Transition cost from IPv4 to IPv6?
 Cost for keeping IPv4?
– Operation cost
– R&D cost for NAT, etc.
IPv4
Transition cost
IPv6
It’s like energy level
transition in chemical
reactions.
Example of Home Appliance (I)
 HA utilizes contents from the network
 HA is upgraded from the network.
– Like a COMPUTER
HA vendor server
 HA will grow according to user’s
preference

Server by
Recipe Provider
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

・healthiness of power unit
Food Industry
Market research
Neighborhood Community
(Grocery store, etc.)
One-to-one marketing & sales
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

Users
IPv6 and Mobile Terminal
 Personal interface to the IPv6 network
– 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.
Applications are emerging
IPv6Car(Wide Project)
PlayStation Game(SONY)
IPv6 VoIP
IPv6 Toy Train (TOMY)
Pictures provided by Kame project, NTT and RIIS
IPv6 Refrigerator (Toshiba)
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
Future
 A lot of opportunities for new
applications and your business!
