Vint, when I may ask you directly: I frequently read your catenet model
for internetworking and your paper with Bob Kahn from 74.

I'm still to understand your position towards flow control between
adjacent (IP-)nodes and the subnets as well. We eventually agreed that
subnets must not do flow control (but discard packets, which cannot be
served) in order to avoid head of line blocking. Would it make sense
(though it might not be possible for practical reasons) to assume /
employ a flow based flow control which would even work in and through
the concatenated subnets?

So we wouldn't have a best effort packet switching but (in a sense) some
kind of "flow switching"?
