[Roll] Comments For ROLL terminology-06

[Abdussalam Baryun <[e-mail]>]

Hi Vasseur, and All,

Comments:
+++++++++

AB>general comment> ROLL is about routers/nodes/hosts Why not defined
:  Host, Node, Link, Interface

In the body of draft-06:-

Closed Loop Control: A process whereby a device controller controls
an actuator based on information sensed by one or more field devices.

AB>suggest> replace [process] with [procedure]
AB>suggest> replace [information] with [input information]

Downstream: Data direction traveling from outside of the LLN (e.g.
traffic coming from a LAN, WAN or the Internet) via a LBR.

AB> suggest> remove the example, because first, ROLL is inside LLN not
outside, and second, most of the data-traffic MAY go from the LLN to
the Internet/LBR. IMHO downstream is in the direction of the havier
unit-flow.

AB> please note that if we use word [data] is different than
[message]. While using [message] we may mean all traffic includes data
and control messages, so the use of downstream and upstream as in
draft-06 will be ok, but if we mention data-direction IMHO the use
downstream-upstream will be the other way around.

AB> suggest> replace [data] with [message]

Field Device:

AB> delete word> field

MP2P: Multipoint-to-Point is used to describe a particular traffic
pattern (e.g. MP2P flows collecting information from many nodes
flowing inwards towards a collecting sink or an LBR).

AB>opinion> MP2P is not a traffic pattern it is a transmission method

I am not sure if the draft covers all terms used in ROLL protocols, I
will check and post on the same thread after. Thanking you,

Best Regards
