Summary: Has a DISCUSS. Needs 6 more YES or NO OBJECTION positions to pass.
** Section 2. Rank Priority and Pan Priority. Can you please clarify whether a higher or lower number indicated an increased priority: -- Rank priority says “Lower values are better” -- What does “better” mean? Is a lower number more or less willing this 6LR is to serve as the RPL parent? -- Pan priority doesn’t include guidance on whether a higher or lower number indicate increased priority. ** Section 2. network id. Can you please clarify the computation of the default value using SHA-256. The text initially says that network id is a “variable length field, up to 16 bytes in size”. Later it says that “the network ID can be constructed from a SHA256 hash of the prefix (/64) of the network. That is just a suggestion for a default value.” However, a SHA256 hash has a 256 bit output which can’t fit into a 16 byte field size. Is there a truncation?
** Section 2. Rank Priority. This is a local value to be determined in other work. It might be calculated from RPL rank, and it may include some modifications based upon current number of children, or number of neighbor cache entries available. -- what’s a local value? What’s the other work? -- the follow on sentence of “It might be … “ doesn’t seem decisive in the guidance. Would it be cleaner to say, that the computation of this value is out of scope of this document. ** Editorial -- Please review Yoav Nir’s SECDIR feedback -- Abstract. Per “Nodes in the TSCH network typically frequently transmit …”, likely only “typically” or “frequently” is needed. -- Typo. s/the the/the/g
— Section 1.2 — The EB is used by nodes already part of a TSCH network to annouce its existence. I can’t figure out the antecedent to “its”. Can you rephrase this sentence to make it clearer? There is a limited number of timeslots designated as a broadcast slot by each router in the network. While “a limited number” looks as if it should be singular, it is generally considered plural in usage and needs “are”, not “is” (and the plural “broadcast slots”). This is a tricky one... You should also get rid of the “/s” later in the paragraph. — Section 1.3 — if a pledge node does not hear an RA, and decides to send a RS You should be consistent in use of “a” or “an”, and I think “an” works better. In the numbered list, each item is a complete sentence and should start with a capital letter. You also should fix the sentence capitalization throughout Section 2. This document defines a new IETF IE subtype Please expand “IE” here. — Section 3 — The Enhanced Beagon Typo... validate the beacon, providing them with a trusted The end of that sentence is missing.
Thank you for the work put into this document: it seems simple and easy :-) Nevertheless, please find below some non-blocking COMMENTs (and I would appreciate a response from the authors) and NITS. I hope that this helps to improve the document, Regards, -éric == COMMENTS == -- Abstract -- "announce the presence of the network" makes me wonder... Do nodes announce the network ? or do nodes announced THEIR presence in the network ? or do router nodes announce the network? or am I too unfamiliar with TSCH ? -- Section 1.2 -- Please expand "ASN" at first use. I guess that this is not the usual AS Number ;-) -- Section 1.3 -- Please add a reference for "broadcast aloha slot". Isn't the word "IETF" in "defines a new IETF Information Element (IE)" redundant in an IETF document ? -- Section 2 -- "that need addressing via unicast Router Solicitation messages" is unclear to me... Is to do SLAAC ? or look for an actual router? Add a reference + acronym expansion to RPL at first use. "This field provides the suffix (IID)" please expand interface ID and, on my side, I do not like naming the IID as a suffix. -- Section 5 -- Reading and applying RFC 8126 (how to write IANA considerations) would be beneficial. == NITS == -- Abstract -- Suggest to expand TSCH at first use. -- Section 1.3 -- Unsure whether "reasons: First, there" should have a capitalized "First". There are also many acronyms that should be expanded at first use (I stopped commenting about those).
