Thanks, Jim,


I've been following the enhanced VPN work in TEAS and I see it as a key
piece of the network slicing work.


It's time that we had some protocol solutions that serve the VPN framework,
and this is a suitable starting point. I like that it is not specifying
additional protocol widgets but has looked at what we already have and is
pointing up ways to use those tools to deliver new function.


I see Robert's point about the resource reservation aspects of traffic
engineering applied to an SR network, but this is not an insurmountable
problem. The question might be asked, "Why would you want to do that?" but
that is a question that (as Yakov would have said) the market can decide. It
seems that there are a couple of vendors and a couple of operators who have
an interest.


So I think we should adopt this draft and see whether we can turn it into
something that has great utility.
