Reviewer: Brian Trammell Review result: Ready with Nits This document has been reviewed as part of the transport area review team's ongoing effort to review key IETF documents. These comments were written primarily for the transport area directors, but are copied to the document's authors and WG to allow them to address any issues raised and also to the IETF discussion list for information. When done at the time of IETF Last Call, the authors should consider this review as part of the last-call comments they receive. Please always CC tsv-art@xxxxxxxx if you reply to or forward this review. This document is ready from a transport standpoint. It describes an already-implemented, relatively-straightforward application of an existing BCP to a well-understood protocol, and is clearly written. I especially appreciated the complete set of considerations, covering situations in which NTP port randomization could cause issues with certain deployment scenarios. The effect of routing on NTP is well studied (one such study is cited in the draft), and sections 3.3 and 3.4 discuss how this draft could interact with on-path modification of NTP traffic. Herein lies my only nit with the draft: it would be nice if 3.3 and 3.4 discussed how an NTP-speaking endpoint could detect and react to issues caused by misconfigured filtering or NAT. -- last-call mailing list last-call@xxxxxxxx https://www.ietf.org/mailman/listinfo/last-call
