Minimum Requirement of IPv6 for Low Cost Network Appliance draft-okabe-ipv6-lcna-minreq-01.txt Atsushi Inoue inoue@isl.rdc.toshiba.co.jp Toshiba Corporation R&D Center
Contents Motivation Changes from -00 draft Open issues Next steps
LCNA definition Low Cost Network Appliances (LCNA) will be connected to the Internet - Special purpose devices (unlike ordinary PC).
- Having limited network functionality under limited resources.
- Not a router, but a host.
LCNA example (Home appliances)
LCNA example (Home appliances)
LCNA example (IP sensor) SIMM size 1MROM 1MRAM 8bits,40MHz IPv4: 7KB IPv6:21KB JVM HTTPD, Telnet, Ftp
Motivation In Japan, many LCNA trials are promoted as a national project. - http://www.v6pc.jp/
- IP Sensors
- Home appliances (Refrigerator, Microwave oven)
- Playstation2 w/ IPv6 functionality
- Currently prototyped w/ KAME/USAGI full-spec IPv6 stack
- But in order to make them commercial products, cost down by compact implementation (including LSI packaging) is necessary
Our objectives Submit a LCNA node requirement document in order to make a guideline for implementing IPv6 on LCNAs. - Sharing implementation experience of various LCNAs.
- Making reference code and test suites to public
- Drive LCNA industry
- LCNA Interoperability test (Jan.23-26 @Pacifico Yokohama)
- 27 organization joined with 7 LCNA implementations (from 6 organizations)
3rd TAHI IPv6 Interoperability Test Event
Changes from -00 draft Reflected comments of IPv6 WG Mobility parts (2.8, Chapter 5) are appended Default address selection for IPv6 (3.8) is appended Security part is completely changed - Threat analysis of LCNA (4.1)
- IPsec not mandatory (4.2-4.3)
- IPsec minimum requirement in 00 draft is now moved to Appendix as one (IP-layer) example of security solution (but we cannot mention about other layers’ security solutions)
Open issues (IPsec mandatory ? ) - Discussion of cellular draft also works for LCNA
- Basically, IPv6 mandates implementing IPsec.
- No-IPsec must not be allowed even if currently LCNAs cannot support IPsec
- On IPv6 end-to-end environment, no-security nodes cannot exist (it might be victim of intrusion/highjacking)
- It might happen that a vendor have to limit (or omit) IPsec implementation on its own responsibility.
- If IPsec minimum specification is regulated, draft-00 (ESP with manual key exchange) will be fine
Open issues (document structure) - Is generic node requirement document possible ?
- In case of cellular draft, usage model and network configuration are regulated by 3G network document
- But in case of LCNAs, we have not discussed network/usage models yet
- We need descriptions for network/usage models of typical LCNAs
- Home appliance LCNAs and home gateway model
- Sensor type LCNAs and information gathering server model
- Should these items be merged to this draft ? Or separate documents ?
Next Steps On 02 draft - Update Chapter 4(Security) again
- Update Mobile IPv6 part by watching mobileip WG progress
- Network/Usage model description (on separate document ??)
- Security solution evaluation data on appendix
- How difficult it is for LCNAs to implement current security solutions must be evaluated !!
After that, proceed to WG item
