Speaking as both myself and a WG chair, not sure where to draw the line.

I have reviewed the document.  Technically, it looks quite clear, I have some comments on how to fit this into the bigger picture though:

1. The reason for publishing this draft is to document the work done by the
   authors in a permanent way.  The WG has reviewed the document to verify
   that the description of the work done is clear.

   The document is not published as "the WG consensus solution" to a
   specific problem, as there is no consensus amongst the WG on what
   the problem is.  There has been no discussion and there no
   consensus either if this solution is the one the WG prefers.

   The abstract and introduction should explicitly says this.

   What I want to avoid, is that this gets to be the
   de facto standard without WG consensus on the problem or the solution.

2. The IANA section can be dropped.  Yes, there is a registry and the
   authors made private extension to it, but now that the experiment is
   over, they can be removed again, and IANA doesn't have to do anything
   now.

3. I think it would be good to mention that there is a working prototype
   implementation of these extensions, with a reference if that is at all
   possible.  The document should say that it describes the prototype as
   it was on the day the document was written.

   I did noticed changes in the protocol extensions over the versions.
   Is this because the prototype was modified?

Henk

There appears to have been a collective retreat from reality that day.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the IP Performance Metrics Working Group of the IETF.

        Title           : TWAMP Value-Added Octets
        Author(s)       : Steve Baillargeon
                          Christofer Flinta

        Filename        : draft-ietf-ippm-twamp-value-added-octets-01.txt
        Pages           : 16

   This memo describes an extension to the TWAMP test protocol for
   identifying and managing packet trains, which enables measuring
   capacity metrics like the available path capacity, tight section
   capacity and UDP delivery rate in the forward and reverse path
   directions.

   This memo is the product of a working prototype. It does not
   represent a consensus of the IETF community. The IETF community is
   currently working on the problem statement and has not reached
   consensus on the preferred method for measuring capacity metrics.
