Contents Motivation Objective of this draft Changes from -00 draft Open issues Next steps

LCNA definition: 

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) Toshiba Internet Refrigerator

LCNA example (Home appliances): 

LCNA example (Home appliances) Panasonic Internet Microwave Oven

LCNA example (IP sensor): 

LCNA example (IP sensor) SIMM size 1MROM 1MRAM 8bits,40MHz IPv4: 7KB IPv6:21KB JVM HTTPD, Telnet, Ftp Yokogawa IP sensor


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: 

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. How to select necessary functionality under certain resource limitation 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: 

3rd TAHI IPv6 Interoperability Test Event

Changes from -00 draft: 

Changes from -00 draft Reflected comments of IPv6 WG Corrected several editorial errors 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) LCNA must support appropriate security solution depending upon the contents of communication and operation capability 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 ? ): 

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): 

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: 

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 Target for Informational RFC or BCP
