Extrapolating from a single connection-oriented protocol over point-to-point links to "ANY networking application" is quite a stretch! What about connectionless protocols? What about protocols that expect a broadcast medium? [[ Sure, it's possible to put ATM into routers. We just build a virtual circuit to every host we talk to and run the IP traffic over that. And if we can put it into routers, we can put it into hosts. But what's the point of that -- we've just added several complicated layers with new limits and no increase in functionality. ]] -- Donald Becker becker@cesdis1.gsfc.nasa.gov USRA Center of Excellence in Space Data and Information Sciences.
