5 2001.8.10 http://www.i-node.co.jp/5 Future of the Internet in Japan 30 million households will have broadband access to the Internet by 2005. Goverment IT Policy: http://www.kantei.go.jp/foreign/it/network/priority-all/2.html http://www.kantei.go.jp/foreign/it/network/priority-all/2.html Changes: Diverse/innumerable devices on the Internet New services Influence upon business: New applications and services Marketing Security

6 2001.8.10 http://www.i-node.co.jp/6 Outline: When broadband access is deployed What will happen? What will be new requirements? Will IPv6 be necessary? Will micronode w/ IPv6 have reality? What micronode can be possible? What is issues/challenge?

7 2001.8.10 http://www.i-node.co.jp/7 New Requirements for Users Network device must be “ easy-to use ” if people of 30 million home use the Internet practically: User can use the devices w/o special knowledge about PC, OS and network. The devices must be non-PC (=specific purposed) network appliances. The devices must work under limited resouces (power consumption, performance, size, etc … ). Every single user can have number of devices. The devices can have end-end communication.

8 2001.8.10 http://www.i-node.co.jp/8 Micronode has network functionality Plug & play is non-PC device No need OS and PC knowledge Small and/or simple Specific purposed Limited H/W and S/W resources PC is not a enemy, but a friend

24 2001.8.10 http://www.i-node.co.jp/24 Possibility of the micronode Our micronode can combine with CCD device Microphone/Speaker IR controller Environmental monitor (ex. air pollution, temperature) Bio-monitor (ex. heartbeat, breathing) IR Controller Environ. Monitor Inter- net Server

26 2001.8.10 http://www.i-node.co.jp/26 Issues/Challenges (1/6) Managing huge number of nodes Some application need servers to manage micronodes. More than 10^5 micronodes (1% of the government ’ s goal) Servers can not gather data from huge number of nodes by real-time fashion. Every single micronode have to be smart for rate limitation.

27 2001.8.10 http://www.i-node.co.jp/27 Issues/Challenges (2/6) IPv6 Minimum host spec. Entire IPv6 spec. can not be implemented under limited resouces. What part of spec. is mandate? Harmless to other IPv6 nodes Reasonable to the future of the Internet http://www.tahi.org/minspec/

28 2001.8.10 http://www.i-node.co.jp/28 Issues/Challenges (3/6) Security bottom line IPsec is too heavy for our micronode because of limited resources (especially performance). Authentication is mandate. Encryption may NOT be mandate. From business point of view, NAT and IPv4/IPv6 translator should not be ignorable. It also discourages use of IPsec. Current solution: Security functionality in application layer

29 2001.8.10 http://www.i-node.co.jp/29 Issues/Challenges (4/6) Updating firmware from remote site There are many reasons to update firmware. Bug fix, new function, new service, …… Legacy way of support (on-site or send- back) will not match cost because of huge number of micronodes.

30 2001.8.10 http://www.i-node.co.jp/30 Issues/Challenges (5/6) Updating firmware from remote site (Continued) To be considered Low impact against the network Recovery from update fails Scalable Re-using/combining existing technologies We do not see right answer yet.

31 2001.8.10 http://www.i-node.co.jp/31 Issues/Challenges (6/6) To be implemented DNS Discovery NTP
