Do we have any of the necessary software parts to do simulated ATM
hardware similar to what if_tap does for Ethernet? Using the VIMAGE
stuff and virtual ATM hardware might open up the door to a more
accessible development and test environment. I did the NATM locking
work essentially "blind" due to a lack of test environment locally,
which seemed to work out, but a software test system would go a long way.
Loopback would be possible, sure, but you are probably only going to be
able to simulate looped-back PVCs.
Fortunately, the ITU G.DMT mandated use of ATM for xDSL generally only
uses PVCs.
But for SVCs, forget about it.
The really cute thing about ATM always was :
the ATM Forum made end-station specs relatively freely available --
but, like X.25, the machinations of switching were left up to the
vendors.
ATM switch simulation is "another project entirely".
