If I get your drift right, you're saying that X.25/LLC (and
similar CO networks) aren't sufficient for the B-ISDN of the
future, yes?

What I surmise, particularly from Dave Cheriton's Blazenet writings
and from AT&T/Bellcore's current work on high-speed switching fabrics,
is that we must begin to look at protocol architectures that exploit
the coming broadband media. Not just live with multi-megabit
networks, but push them for all they are capable of. I guess I'm
not sure X.25 is capable of that, nor is a 128-octet LAP. How we
engineer upper-layer protocols for extraordinarily reliable,
high-volume, low-latency traffic makes for interesting and important
research, seems to me.

Next question is, who's going to pay the bill for building these
behemoths? (Sorry folks, that's a big word for a big animal.)
And who's going to set an agenda for exploring what we can do with
