Hi,

I have reviewed this document as part of the Internet Area 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.

This document describes an extension to the simple TWAMP protocol to support its use in both MPLS and IPv6 segment routing networks in cases where it is desired that the STAMP packets follow the same path from sender to reflector and back again.

The document serves a useful purpose, is well-written, and Ready for publication.

Minor comment: the abstract could make it clear that the extension is to enable the same path to be taken out and back between sender and reflector.

Tim
