In article <DE7895D0-0EBB-4C78-9944-0DC203E14C37@strayalpha.com> you write:

The problem is when you have networks connected A-B-C, network A sets
the header for deluxe service, then complains to B that C isn't
providing the service they're paying for.  What service? says C.

I realize that in the real world there's tons of VPNs and overlays
that provide various sorts of guarantees but they're a direct
arrangement between a customer and the network providing the service.

R's,
