Hi Xavi and all,

I have just read the Minimal 6TiSCH draft at
https://bitbucket.org/6tsch/draft-vilajosana-6tsch-basic/src. Here are my
comments.

Typos:

(1) In section 2,  “2. Minimal schedule” => “2. Minimal schedule
configuration”

(2) In section 2.2, “has a bitmap of cell options assigned.”  => “has a
bitmap of cell options assigned, named LinkOption.”

(3) In section 3.2, “Frame and Link IE” => “Frame and Cell IE”

(4) In section 5.3, “The Slot and Link IE contains the ASN and 1 Byte field
named Join Priority.” => “The Sync IE contains the ASN and 1 Byte field
named Join Priority.”

Questions:

(1) In section 5.1, ETX is a measure for calculating OF, or a OF?

(2) need some sentences about how to set DAGRank to Join Priority.

In IEEE802.15.4e, table 52b, Range of Join Priority is 0x0000~0x03ff. I’m
not sure if it is a fixed range. If yes, we need to do something or say
something in the draft.

Thanks

Qin
