Re: [Lwip] I-D Action: draft-ietf-lwig-cellular-01.txt

Dear Ari,


I just roughly went through the draft. It is an interesting draft. I think
it is a good

approach to summarize the cellular and power efficiency for CoAP
implementation.

Following are some general comments.


1. There are personal drafts referred in this document. Some are not active
now,

for example, draft-vial-core-mirror-proxy, draft-castellani-core-alive, and

draft-fossati-core-publish-monitor-options. However in this draft the three
drafts

are described as the main candidate solutions in Chapter 8.

I think it better to focus on the delegation model description in this
chapter and

avoid talking about solutions since there is no consensus on solutions.

If necessary, the three personal drafts can be used just as example
approaches.


2. The draft is focusing on power efficiency according to the abstract.

However chapter 5 seems to talk about cellular constraints.

the relation with power efficiency is not clearly identified. There should
be

some words describing the role for discovery and registration in

the power efficiency context. Also it is better to add a few word in

the beginning of chapter 5 to clearly indicate that this draft focuses

on CoAP devices in cellular network.



Thank you.

Regards

Yuanchen
