# OPSDIR review of draft-ietf-taps-arch-18 I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in the last-call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last-call comments. The document is clear and well-written. The motivation is described well. The architecture is clean. I did a review of the -17 version. All comments and nits identified are handled by the new version. I made a suggestion to think about adding an explicit section for Operations and Manageability. But I assume the authors did not think it was useful for an API architecture document and that's okay. But I would have appreciated a reply anyway. Thanks! Dhruv
