Re: [re-ECN] Conex charter

I agree with John pretty much. Since I have been looking at CONEX, that
would imply that my employer has at least some minimal interest in CONEX
technology. But to make the leap that my employer is committed to deploy
this technology is a huge leap.

Remember: the current charter text states that the current expected work
outputs are "Informational" and "Experimental" documents, so I'm not
even sure what you mean by "deployment".

Here are some (purposely snarky) responses, to show why it is hard to
answer, and why these are BUSINESS QUESTIONS outside of the scope of our
group:

(Let's NOT discuss these questions on the list!!!)

Is there a list of vendors that have stated that they plan to implement
CONEX technology in their products? Is there a list of vendors that have
stated that they have no plans to implement CONEX technology in their
products?

For the vendors that are planning to implement CONEX, what CONEX
features will be implemented? What is the CONEX implementation roadmap?
What is the additional cost for CONEX features (by product, by feature),
or alternatively will certain CONEX features be 'table stakes' for
certain vendors?

Again, let's NOT discuss these questions on the list!!!

   I am not aware of such a list, although the ISP I own (JLC.net)
should
certainly be included.

   In fairness, ConEx is very much a moving target right now, so I'd
hesitate to push any of the ISPs I talk with to plan adoption of it.

   I don't know... this has the same moving-target issue...

   In fairness, I don't think it matters much whether any individual
ISP deploys it. It is about visibility of congestion information, not
about what anyone might do with it. For myself, I always want to stare
at data for a while before attempting to automate anything.

   Good question!

   My personal view is that ConEx makes absolutely no difference except
at IP-layer forwarding points; so I can't imagine why I'd want to view
it (least of all change it) at MPLS layer.

   (I'm only partly familiar with how ECN is carried through MPLS layer
in the EXP field; but I can't think of anything useful to do about it
until the return to IP-layer forwarding.)
