Document: draft-ietf-pals-ms-pw-protection-03 Reviewer: Peter Yee Review Date: Oct-15-2015 IETF LC End Date: Oct-15-2015 IESG Telechat date: Oct-22-2015 Summary: This draft is basically ready for publication as a Standards Track RFC, but has nits (and a question) that should be fixed before publication. [Ready with nits] The draft provides two mechanisms that can be used to provide protection to static Multi-Segment Pseudowires against failure of switching Provider Edge nodes. I'm not familiar enough with the topic to determine if the mechanism works as easily as described in the draft, but the concept helpfully does not require invention of new protocols, so a determination of suitability shouldn't be difficult for MPLS experts to make. Question: Wouldn't it make sense to provide some explanation in Appendix A for why it exists and when it should be used? Currently it's just offered as an alternate approach without real guidance. Major issues: None Minor issues: None Nits: General: Expand all acronyms on initial use. Some of them are probably well-known in the MPLS community, but their expansion wouldn't hurt either. Specific: Page 4, 1st paragraph, 1st sentence: replace "MS PW" with "MS-PW" to match other usage in the document. Page 4, 2nd paragraph, 2nd sentence: append commas after "which" and "PWs". Page 4, 3rd paragraph, 1st sentence: replace the comma with a semicolon. Page 8, Section A.2, 1st paragraph, 1st sentence: append a comma after "link". Page 8, Section A.2, 2nd paragraph, 1st sentence: append "entity" at the end of the sentence. As it is, the sentence ends ambiguously in an adjective. Page 8, Section A.2, 3rd paragraph, 1st sentence: change "a SS-PW" to "an SS-PW".
