Hi Alfredo,

I don't think  WirelessHart and ISA100.11a can be added on top of 6top. The
reasons are:

(1) They have their own and different protocol stacks.
(2) They use Timeslotted channel hopping technology, but not IEEE802.15.4e
TSCH.

So, according to my understanding, the problem is how IPv6 protocol stack
can take advantage of TSCH, which has been proven good and standardized by
IEEE.

Thought?
Qin
