Since its announcement in 1974, Systems Network Architecture (SNA) has evolved in terms of its functional content, configurational flexibility, and network management services. This paper briefly traces this progress to the present and examines the more recent advances in greater detail. It then discusses known requirements for enhanced application and transaction services, for additional provisions for very large networks, for continuing adaptation of small-system and transmission media advances, for inclusion of additional management capabilities, and for further integration of network standards—all of which will shape future SNA developments.
