Common Communications Support in Systems Application Architecture
by V. Ahuja
Application execution in a Systems Application Architecture (SAA) network depends on the underlying capability of the network to obtain reliable connectivity and orderly data exchange among its system components. The objectives of SAA are distributed applications, distributed processing, and distributed data, which are achieved through interconnected SAA systems supporting appropriate interfaces and architectures. The Common Communications Support of SAA affords this capability by utilizing a number of Systems Network Architecture communication architectures and international standards. These architectures provide useful data interchange within SAA components by providing services ranging from managing data links to specifying data streams for user applications. This paper discusses the role of Common Communications Support and the means for SAA users to access this support, and provides an overview of the functions and roles of various component architectures of Common Communications Support, along with their interrelationships.
