Dear Dominique. Thanks for your valuable comments. These comments will be helpful to improve the draft.
Please, find my response inlines. I will update the draft to resolve the comments in a next revision. Best regards. Yong-Geun.

I guess the existing sentence looks like a little ambiguous. The sentence you proposed looks like a more better.

In previous version (04) of this draft, it includes LTE MTC as one of example of a potential candidate but we decided to delete the potential candidate and focus on current 6lo link layer technologies. I will update the paragraph based on your comments. > > - Section 3.7 "The following table shows that dominant paramters of > each use case corresponding to the 6lo link layer technology". > Incorrect sentence. > > [Yong-Geun] Yes, this sentence includes typos and unclear expression.

To provide more correct information, it will be better to describe common (general) characteristics of each technology. But, in some point, we have a difficulty to capture common characteristics of each technology for different application in limited space. That is the reason why we mentioned the usage of each technology in the first row. I will discuss other authors and try to find best way. > > - In what respect are section 4 and 6 different?

The main intention of section 6 is to provide 6lo use case examples of each 6lo link layer technology. But, in the section 6, we cannot guarantee the real deployment of described use case examples. That’s the reason why we provided the section 4. The main intention of section 4 is to provide *real* and *real* 6lo deployment scenarios and it includes G3-PLC and Netricity. So, the purpose of section 4 and section 6 is different. In my opinion, it is better to keep the separated sections. > > - Section 10.1, Normative References.

The main Normative reference are related in section 5 Guidelines for adopting IPv6 stack. As you suggest, I will check again and seek advice. > Best regards > > Dominique > > _________________________________________________________________________________________________________________________ > > Ce message et ses pieces jointes peuvent contenir des informations > confidentielles ou privilegiees et ne doivent donc > pas etre diffuses, exploites ou copies sans autorisation.
