Hello authors, Apologies for late comments. May be we can talk about the detailed review later, instead I wanted to discuss high-level points first. Please take them as comments from a newbie...
1. I found it bit challenging to catch up with all the past 4-digit RFC-soup that this document need to reference (3 from SCHC, 3 from base 6lowPAN, a few on RPL). It becomes arduous to follow everything (I had to read 4 to 5 documents before getting reasonable understanding on how I could help with review). I am not sure how can this be addressed but something to consider as a broader assumption when writing the document. 2. One suggestion is to re-write architecture section. 2.1. Since 6lowPAN is using SCHC, I find it odd that it does not talk about adapting SCHC architecture in LLN. i.e. say what node will need to support what SCHC functionality. Then the document will become easier to read. For instance, you could draw a LLN with 6LRs, BRs etc. and say what SCHC gateway functionality will fit where instead of saying in straight-forward RPL rules should be installed in all LRs... 2.2 So I suggest first present both the architecture then map functions will be better and then develop cases. 2.3 Ques: how are SCHC rules distributed in LPWAN? Can same techniques be used or RPL is the only approach? (sorry, I am not finished reading SCHC and don’t know this yet). 3. I would have really liked to see 'SCHC dispatch' discussed earlier as part of the architecture instead of dealing with it later. This is a key LLN dataplane enhancement and everything builds on top of it. The key is you are not adding new rules, you are using LLN data plane to carry SCHC and nodes with knowledge of this feature will process accordingly. To summarize, when you put this together, reading of document will be very simple: - adapt SCHC architecture - describe new dataplane enhancement - describe routing mechanisms - formats... What do you think? It's possible I must have misunderstood, in that case please bear with my ignorance :-). Thanks Kiran
