They run on the same hardware (at the same time, even) but cannot talk to each other at any level. OSI is a connection based protocol developed in Europe. It is relatively new, and there is damned little support for anything using the OSI protocol stack. We use a network that runs the OSI stack on Ethernet... it's pretty nice, but isolated. By dint of running two sets of networking software we are able to communicate with the real world of... DDN is a connectionless protocol developed by the DoD. It's usually referred to as TCP/IP because the basic packet switching and reliable comminucation protocol go by those acronyms. It was developed ad hoc over many years and is now quite reliable and widely available. The Ethernet software available for the Amiga talks DDN... ...which is why it would not be able to run on an OSI network. No great loss: OSI is not terribly important these days. -- Peter da Silva. `-_-' .
