Hi, Thanks for your review. The v07 I just posted addresses your comments. Brgds, -----Original Message----- From: Melinda Shore [mailto:melinda.shore@xxxxxxxxx] Sent: Thursday, October 05, 2017 00:09 To: secdir@xxxxxxxx Cc: draft-ietf-rtgwg-uloop-delay.all@xxxxxxxx; ietf@xxxxxxxx; rtgwg@xxxxxxxx Subject: Secdir last call review of draft-ietf-rtgwg-uloop-delay-06 Reviewer: Melinda Shore Review result: Has Nits This document describes a mechanism to mitigate against failures stemming from the formation of "microloops" during a re-routing convergence, as described in RFC 5715. Modulo some mechanical problems with language usage (i.e. grammatical errors) and some missing definitions, the document clearly describes the problem it is addressing and the proposed solution. The security considerations section is very clear about why the authors believe no new attacks are introduced by this mechanism, and it is credible Sections 4 and 5 represent the core of the document and are very clear - a very nice piece of specification. It would be helpful to have a terminology section, or to expand some of the acronyms in-line (LFA, for example). For some reason the grammatical errors are clustered towards the front of the document but there are many scattered throughout: Section 1, first paragraph singular/plural mismatch: "Based on network analysis, local failure make up a significant portion of the micro-forwarding loops" Section 1, second paragraph unidiomatic use of "the topology" Section 2, first paragraph unidiomatic use of "high damages" Section 2.1, first paragraph needs an article on "IGP shortcut" Same paragraph, doesn't need an article on "the router C" Same paragraph, "nexthop" should be two words Item 1 in 2.1, needs an article before "preprogrammed FRR path", also run-on sentence needs to be split or a conjunction inserted Item 3 in 2.1, "no more" should be "no longer", and "encapsulate anymore" should be "does not continue to encapsulate" Section 2.1, last paragraph: "The protection enabled by fast-reroute is working perfectly, but ensures a protection, by definition, only until the PLR has converged." is somewhat unclear Section 3, third paragraph: first comma is unnecessary. Also, "local only" should be "local-only" Section 8.2, first paragraph: "associating timing" should be "associated timing". Also in section 8.2, the message chart header is separated from the actual contents by a page break, and that should be remedied Section 8.3, first paragraph: "that happens" should be "that happen". Also, "without further delaying route insertion" would be more idiomatic than "without delaying route insertion anymore" Section 9.1, throughout: "nexthop" should be "next hop" Section 9.1, first bullet item: "only have one" should be "only has one" (or "has only one") Section 10: "a good behavior" should be "good behavior" _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
