Reviewer: Menachem Dodge Review result: Has Nits Reviewer: Menachem Dodge Review result: Has Nits I have reviewed this document as part of the Ops area directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the Ops area directors. Document editors and WG chairs should treat these comments just like any other last-call comments. The document defines an additional 4 IPFIX Information Elements in order to export measured delay of packet flows at transit and decapsulating nodes. The document is readable and understandable. Nits ==== 1. In the first paragraph of the introduction section the word "need" is used twice but I believe that it should be "needs" with an 's'. 2. I believe that the introduction would be clearer if the instructions to IANA about the new elements were not included in the Introduction section but left for the IANA section later in the document. I also think that the measurement interval period should be mentioned in the introduction and added to the diagram in Figure 1. 3. In section 3.3.5 it was not clear to me how the T0 and Tf are determined by each node. Section 7.4 Measurement Interval does not explain what triggers the start and end of the measurement interval. But maybe I have missed this. 4. Section A.1 the title: "Aggregated On-Path Dealay Examples" should be "Delay".
