[6tisch] 6TiSCH Protocol Stack in draft-ietf-6tisch-architecture-12

[Yasuyuki Tanaka <[e-mail]>]

Hello Pascal,

I have one minor comment on Figure 1 of the draft;

   https://tools.ietf.org/html/draft-ietf-6tisch-architecture-12#section-3.1

My suggestion is to put "6LoWPAN HC / 6LoRH" directly on "IEEE Std 
802.15.4 TSCH" and to add one box labeled with "Scheduling Functions". 
It would look like...

(suggested version)

       +-----+-----+
       |    COMI   |
       +-----+-----+-----+------+-------+-----+
       | CoAP/EDHOC/COSE |  6LoWPAN ND  | RPL |
       +-----+-----+-----+------+-------+-----+
       |       UDP       |        ICMPv6      |
       +-----+-----+-----+-----+-------+------+------------------------+
       |                 IPv6                 |  Scheduling Functions  |
       +--------------------------------------+------------------------+
       |        6LoWPAN HC   /   6LoRH        |      6top protocol     |
       +--------------------------------------+------------------------+
       |                     IEEE Std 802.15.4 TSCH                    |
       +---------------------------------------------------------------+

(current version)

       +-----+-----+
       |    COMI   |
       +-----+-----+-----+------+-------+-----+
       | CoAP/EDHOC/COSE |  6LoWPAN ND  | RPL |
       +-----+-----+-----+------+-------+-----+
       |       UDP       |          ICMP      |
       +-----+-----+-----+-----+-------+------+----+
       |                 IPv6                      |
       +-------------------------------------------+
       |             6LoWPAN HC   /   6LoRH        |
       +-------------------------------------------+
       |                   6top                    |
       +-------------------------------------------+
       |             IEEE Std 802.15.4 TSCH        |
       +-------------------------------------------+

"ICMP" is replaced with "ICMPv6" as well.

Thanks!

Best,
Yatch
