Regarding the above URL and a message I posted last week, does anyone
have a list or outline of the functions, or even better an architecture,
of an MPLS forwarding device ("native MPLS switch") that does not depend
on ATM, FR or any other L2 transport technology. See figure 1 of the
draft (the right hand column, "2 layers").

Even if no equipment manufacturers and network operators are currently
deploying native MPLS switches or whatever they might be called, the
question still remains as to the design of a switch that borrows routing
control information from, say, IS-IS and BGP routers, and is optimized
for forwarding variable-length MPLS packets/frames, and a projected
comparison with the price and performance of IP/POS routers and ATM cell
switches.
