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. 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. Document Reviewed: draft-ietf-ntp-checksum-trailer Status: Ready with nits Summary: This document describes a new NTP extension that adds a 2-octet checksum complement to the end of the UDP payload. I feel the -05 version of this document addressed issues I had with the -04 version. The only other comment is about the examples in Appendix A. I feel the 'Const' referenced there could be expressed in a more descriptive manner, but I am a loss to provide anything better. tim
