Hi Yong-Geun,
Here are some comments on the 6lo-applicability document. 6lo-chairs have been asked to take a close look at the document and I have volunteered to guide the document content along with you/co-authors and WG. We can meet before the 6lo meeting and lay out ideas on the modification. General comment: 1) The document is growing too big and lost focus a bit : we need to make it concise and to the point in relevance with 6lo 2) Editorial changes are needed toward the audience who might have heard of 6lowpan and are interested in finding out whether their application/network is suitable for running 6lo (6lowpan stack with modifications). 3) It talks about LTE MTC and LPWAN technologies as a backhaul gateway where 6lo-type of networks might be one link in the gateway on the LAN side. This is a real-life application. We need to work with LPWAN chairs and provide diagrams to interconnect both 6lo and LPWAN networks 4) The Design section gives ideas on different design attributes which are useful. Now that we have various scenarios with different/TBD attributes, I am thinking that having the same attributes for all usecases may not be required. We may pick one or two examples with complete set of attributes. 5) From the examples, it is not clear where 6lo network and nodes are running in the example. Clarification required. The Abstract: Current Text: This document describes the applicability of IPv6 over constrained node networks (6lo) and use cases. It describes the practical deployment scenarios of 6lo technologies with the consideration of 6lo link layer technologies and identifies the requirements. In addition to IEEE 802.15.4, various link layer technologies such as ITU-T G.9959 (Z-Wave), BLE, DECT-ULE, MS/TP, NFC, LTE MTC, PLC (IEEE 1901), and IEEE 802.15.4e(6tisch) are widely used at constrained node networks for typical services. Based on these link layer technologies, IPv6 over networks of resource-constrained nodes has various and practical use cases. To efficiently implement typical services, the applicability and consideration of several design space dimensions are described. Suggested Text: This document describes the applicability guideline of IPv6 over constrained node networks (6lo) specifications and use cases. It describes the practical deployment scenarios of *multiple* 6lo technologies and identifies the requirements. *A consideration on use-case deployment design dimensions is also described. The aim of this document is to guide an audience who are new to IPv6 low power constrained network technologies and want to assess if the 6lowpan stack can be applied to their constrained L2-technology of interest*. Editorial comments: I have many editorial comments; we can discuss them at IETF 'side meeting'. Other: Section 5 ( Design Space): Please add a sub section on '6lo adaptation consideration'. I can help with the text there. Primarily this subsection may talk about in general what people might think about when they consider running IP(v6) on their constrained nodes (i,e IPv6 address mapping, Prefix distribution, Access security, fragmentation requirements, privacy, L2/L3 topology etc.) What do folks think about a tittle " 6lo Applicability Guideline" instead of " 6lo Applicability and Usecases" ? The goal is to hand out an IETF document to the non-IETF community to spread the word about IETF work on IPv6 IOT stack for constrained networks. Comments are welcome.
