I am the assigned Gen-ART reviewer for this draft. For background on Gen-ART, please see the FAQ at < http://wiki.tools.ietf.org/area/gen/trac/wiki/GenArtfaq>. Please wait for direction from your document shepherd or AD before posting a new version of the draft. Document: draft-ietf-ospf-te-metric-extensions-09 Reviewer: Martin Thomson Review Date: 2014-12-29 IETF LC End Date: 2014-12-24 (nice) IESG Telechat date: 2015-01-08 Summary: Good for PS with some minor issues. Observations: I find it a little disappointing that measurement techniques are so nebulously defined. Values are measured over "a period" using "some method, which might be RFC 6374". The "A" bit threshold is "a configured value". That means that a consumer of this information has to take a lot on faith. I have to assume that this is because we can't do better. Minor issues: Please ensure that all the field descriptions include some textual indication of the size of the field. Type and length are always 16 bits each, so those can be assumed from RFC 3630. As above, please specify the specific IEEE 754 floating point format, i.e., "single precision". Otherwise you have to look at the figures to work out how many bits to use for the value and figures should be strictly informational. Nits: Section 10 is missing a period.
