Panel Discussion
Examining Issues for
Introduction of IPv6 to Home
Users
Global IPv6 Summit in Japan 2001
December 4th, 2001
List of Panelists
• From Terminal Manufacturer Side:
– Mr. Kosuke Ito (Canon Inc.)
– Mr. Atsushi Onoe (Sony Corporation)
– Dr. Akiyoshi Tanaka (Matsushita Electric Industrial
Co.,Ltd.)
– Dr. Kenichi Nagami (Toshiba Corporation)
• ISP side
– Mr.Akihiro Inomata (Fujitsu Limited)
– Mr. Toshiyuki Yamazaki (NTT Communications
Corporation)
• Coordinator
Mr. Tsukasa Ogino (Internet Research Institute/JPNIC)
Current Situation
• Trial assignment and allocation of IP address
• Technical experiment of IPv6 protocol stack
• IPv6 over IPv4 (technical experiment of transition
from v4)
★ Trial service starting from ISP and backbone side
★ Extension and Improvement of IPv6 based on IPv4
experiences
★Explore new applications and markets (Internet
Home appliances, etc.)
Expectations for IPv6 (1)
• IP control equipment vendor side:
– Expansion of business field for communication market
due to increase in IP communication
– Expansion of built-in control units market due to
increase in the targets of IP connection
– Expansion of markets: increase in traffic & sales
• ISP/Administrators side
– Increase in IP end users
(Increase in the targets of IP connection and sales)
– Succession of routing techniques from IPv4 (the
minimum effort of transition)
Expectations for IPv6 (2)
• (Illusion of?) terminal manufacturer side
– Plug and play (free from IP configuration)
– Anything “always” connected (monitoring the state of
devices)
• Access to a private terminal from global, Passive connection)
– Realization of direct IP connection between terminals
– Utilization of IP address like terminal ID, and
management of each terminal in CRM service
– One Stop service in making contract for network
connection service of devices
• Abolition of making contracts for all devices (making users
free from ISP contracts for each device)
• Service charge including IP connection service charge
– Simplification of development based on IP (no
proprietary protocols necessary)
Technical Issues for Popularization of IPv6
1) Ease of Use
How should the user interface be arranged, so that non-PC users do not
need to deal with set up?
2) Network (the way of allocating addresses)
- allocation by ISP
- allocation by device manufacturer
3) DNS
- Who sets up DNS?
- How to have inter-brand compatibility?
4) Security
Certification:
How to certify that a user is the proper user of the terminal?
Support:
Service system: relation between carriers, ISPs, manufacturers, and users
Discussion
• What will IPv6 give to Home Users?
– Home internet appliances?
• What will happen to in-house domestic network?
– For TV, Air-conditioning, etc.
• Who will distribute IP addresses?
– ISP?
– Device Manufacturer -> The serial number = IP address
• What about the security?
– air-conditioning will be controlled from outside

Can we continue this scheme?
• End users have been PC users so far.
– Is it necessary for users to make a contract for each device with ISP?
• It is quite natural that a device manufacturer becomes a service provider.
• DHCP assignment of address from contracted ISP is common.
– A connecting device is PC.
• Easy to implement a function of IP assignment negotiation
– What is the best way to assign addresses to handy IP terminals
brought anywhere such as PDA, mobile phone, Digital Camera, etc?
• Accessing direction from a terminal to global
– The strong needs of accessing so far have been from a terminal to
Internet. From now on, the needs will be not only accessing from a
terminal but also accessing to a terminal.
Dreaming? Model of Net-Business
for a terminal manufacturer
• Providing a network service to a terminal
(terminal control, service billing, etc.)
• Let ISP undertake IP connectivity of terminals and
guarantee the QoS
