[Tsvwg] Re: Last Call: Robust ECN Signaling with Nonces to Experimental

Folks-

I asked a couple of questions about why this document is slated for
experimental earlier today.  After some useful discussion I was
asked to state my opinion on this matter in public (for the record
and for others to shoot at, I presume).

I think this document should go forward as a proposed standard
rather than experimental.

I see the role of experimental as for things that we are just not
sure about.  The recent byte-counting I-D is a good example.  From
everything we know about it, consensus seems to be that it should be
OK.  But, it seems to me that the change is non-trivial enough and
the direction of the questions are in the behavior of TCP in shared
networks and what sorts of effects the change will have on traffic
patterns.  So, going through a period of experimental status seems
fine and prudent to me.

But, it seems to me that the ECN nonce is pretty straightforward.  I
have good confidence that it will not fail in ways that are unsafe
to the global network.  Of course, there is always the possibility
of unforeseen interactions, but my own opinion is that the nonce is
ready for proposed standard (which is not a full standard and we can
still tweak things later).
