Re: [coman] Device Classes?

[Hannes Tschofenig <[e-mail]>]

Hi Carsten,


I am getting more and more uncomfortable with these classes due to the
fuzzy definition.

I wonder whether someone has tried to implement a router with
* an IPv6 stack
* RPL
* security stuff (such as DTLS, EAP, PANA)
* network management protocol (as Thomas was asking for)
* CoAP
* DNS
* software update mechanism
* + the actual application

on a class 1 device.

Ciao
Hannes
