   It is what you think it is, but then again it isn't. ATM provides
its own virtual circuits, so you can skip the overhead of the TCP/IP
stack and protocol. This can buy you a significant speed increase, I'd
imagine, at the cost of having to implement an ATM-specific transport
(to set up the VC, route to it, etc.) in the ORB. You could do the
same for X.25, if you wanted, or even Ethernet or Token Ring if you
only wanted to talk to devices on the local network.
