I am an assigned INT directorate reviewer for draft-ietf-alto-cdni-request-routing-alto-17. These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see https://datatracker.ietf.org/group/intdir/about/. Based on my review, if I was on the IESG I would ballot this document as NO OBJECTION. The following are issues I found with this document that SHOULD be corrected before publication and some comments: I am not particularly familiar with the technology in this draft os I may have missed things. Abstract: I believe it should say "the exact protocol is not specified" adding "not". Section 3.7.1: The second paragraph of this section is one very long sentence that I found confusing and which may be inconsistent. Perhaps a structured list would be better than simple text. Section 6.1.1.2: Seems a bit imprecise. I suggest adding at the end "as a decimal number without leading zeros". I was favorably impressed by the relatively complete information included for the Authors in the Authors' Addresses Section. I wish more drafts did this. The following are minor issues (typos, misspelling, minor text improvements) with the document: PID should be expanded on first use. Although, as far as I can see, other acronyms are appropriately expanded on first use. the document might benefit from a terminology section (maybe 1.1 or 2.3) as not everyone may read the document sequentially and remember all the expansions. Section 2.2, 2nd *'ed paragraph, "ALTO maps can be signed" adding "be". Section 3.6: I don't think the following text is needed and it could be deleted. It merely expresses the default that later IETF documents can modify earlier IETF documents. There may be other documents extending BaseAdvertisementObject and additional CDNI capabilities. They are outside the scope of this document. To support them, future documents can extend the specification defined in this document. Section 3.7.1: /// -> // Section 6.2.1: "to define" -> "defining" Section 10: It is common to include the same information for Contributors as is included for Authors in the Authors' Addresses section but that has not been done. There are a few addition suggestions that I will send directly to the authors. Really trivial: when you have "xyz": stuff for various values of xyz and stuff, there is no consistency in whether or not there is a space before the colon.
