Re: [pkix] Last Call: draft-ietf-pkix-tamp (Trust Anchor Management Protocol (TAMP)) to Proposed Standard

I've reviewed this document as part of the transport area directorate'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 for their information and to allow them to address any issues raised. The authors should consider this review together with any other last-call comments they receive. Please always CC tsv-dir@… if you reply to or forward this review.

I have reviewed this document specifically for any transport related issues.  TAMP is primarily a request/response protocol designed to be independent of the underlying transport mechanism, Appendix C documents using TAMP over HTTP.  In that context, TAMP does not have any transport related issues beyond the underlying HTTP.  As long as the transport over which TAMP is being used is reliable, such as HTTP or TCP, TAMP should be fine.  However, TAMP is documented as being transport independent.  As such, it would be useful if the "Implementation Considerations" sections mentioned any assumptions about the underlying transport.  For example, while the definition of TAMP may be fine for HTTP, I doubt TAMP would work reliably over UDP without the need for additional mechanisms to deal with lost packets.  Just stating that TAMP assumes a reliable underlying transport protocol would probably be sufficient.

Beyond that, I did not see any other transport related issues that need to be addressed before this document is published.
