Hi, 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 per guidelines in RFC5706. Comments that are not addressed in 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. Version: draft-ietf-drip-reqs-12 Overall Summary: This draft is an informational track defining the terminologies and listing the requirements for DRIP. Overall this is a well-written document explaining the requirements and the rationale behind the same. This document does not propose any new standards or extensions to the existing standards and so does not introduce any operational challenges or gaps as such. I am choosing "Has Nits" only to check if the authors can address any of the below observations. Otherwise, it is ready. Few observations below: ==> Is there any reference that you can add to the below-mentioned community documents?. "On this and other terminological issues, to encourage comprehension necessary for adoption of DRIP by the intended user community, that community's norms are respected herein, and definitions are quoted in cases where they have been found in that community's documents." ==> Based on the below DRI suffice, I assume that the below one is defined by this document. "AAA Attestation, Authentication, Authorization, Access Control, Accounting, Attribution, Audit, or any subset thereof (uses differ by application, author, and context). (DRIP)" AAA is common terminology used for "Authentication, Authorization, and Accounting". While they both seem to be similar, is there any need to use a different term to differentiate DRIP-AAA from the traditional AAA?. ==> The text below Figure 3 appears to mention UA-GCS, UA-Internet, and GCS-Internet, but this is not clear in the figure. "Figure 3 illustrates Network RID information flows. Only two of the three typically wireless links shown involving the UAS (UA-GCS, UA- Internet, and GCS-Internet) need exist" Thanks, Nagendra
