Re: ipv6 requirements for a sensor/constrained device

["Arul Kumar Chellappan" <arulkumar.chellappan at gmail.com>]

Dear Julien,

 

Just putting my thoughts and comments are welcome.  I had an opportunity to work on providing IPv6 capability for a tape library appliance.  We were unable to strongly conclude the needed IPv6 requirements for that box.  The main requirement for a IPv6 node is stateless auto configuration and the optional functionalities are stateful auto configuration and gateway configuration. Based on the level of IPv6 functionality a device needs, the IPv6 requirements increase.  If the device needs the IPv6 just for the point to point (master-slave) communication, then just the link local address would be sufficient and I guess the auto config of a global address is not needed. 

 

Hence from my thoughts, the workgroup could first define the minimum and maximum IPv6 functionalities of the a constrained device.  This would help device makers to classify whether the IPv6 capable device that is being developed is a constrained device or a fully capable IPv6 node, and accordingly choose the needed functionalities.

 

Regards,

Hi all,

as a follow up of discussions around 6lowpan and ISA100 standardization, the people in cc and myself are starting an effort to identify minimum ipv6 requirements for a constrained device ( e.g. a sensor), so that ipv6 can be brought to such device. This work would be closely bound to implementation experiments.

This has been discussed a bit within 6lowpan and I know a thread was started in 6man around RFC4294 update. What we would like to clarify is how this work could fit in IETF, in which WG, with whom, as well as the scope and process for this effort.

We would appreciate your feedback on this topic.

Best regards,
Julien Abeille
