UNIX(R) System V Data Networking Architecture

The computer industry is converging on two communications standards - Open System Interconnection (OSI) and Systems Networking Architecture (SNA). OSI will be used in multivendor environments such as factory automation, office automation and telecommunications. OSI is at the heart of the AT&T Data Networking Architecture. SNA will be used to communicate to corporate mainframes. UNIX(R) systems must be able to communicate fluently using both of these standards and must provide a smooth migration path to these standards from current proprietary and national standards.
