[6lo] review of 6lo use cases draft

[<[e-mail]>]

Hello all,

I have read https://tools.ietf.org/html/draft-ietf-6lo-use-cases-08 .
I found it easy to read and informative.
Here are a few comments for your consideration:

  *   I don't think there should be any RFC2116 language in this draft, since it describes use cases. I spotted MAY and SHOULD in Sections 1 and 5.
  *   The bullet list at the end of section 1 is unbalanced: 2 items are full sentences, 2 are just nominal groups
  *   Section 3.6 PLC: "wired technologies are more susceptible to cause interference". More than what technologies? Since wires are meant to guide energy, I would say that wired technologies cause less interference to the radio medium than wireless technologies, all other things being equal.
  *   Section 3.7 "In above clauses, various 6lo Link layer technologies and a possible candidate are described". Unclear which ones are the genuine 6lo technologies, which one is the possible candidate? Does it matter that one is only  "candidate"?
  *   Section 3.7 "The following table shows that dominant paramters of each use case corresponding to the 6lo link layer technology". Incorrect sentence.
  *   Table 2: looks like a mixture of technologies and applications. E.g. latency requirement = low for DECT-ULE, but only true for smart-metering, not for some other DECT-ULE use cases (home automation). Providing only one example of usage is a mis-representation of the technology.
  *   In what respect are section 4 and 6 different? They both have descriptions of technology and use cases. Could they be merged?
  *   Section 10.1, Normative References. I wonder if this draft, being a use case description, should have any normative reference at all (except maybe for RFC2119). I'm not sure, seek advice.

Best regards

Dominique
