This paper presents an overview of AT&T's data networking architecture, called the integrated data architecture (IDA). IDA specifies a flexible networking scheme, compatible with the Integrated Services Digital Network (ISDN), that addresses the needs of users into the 1990s. The architecture specifies functional capabilities and interfaces that provide a total, end-to-end networking solution that is applicable to premises-based and wide-area networks, or combinations of both. In this paper, we describe the major trends that shaped IDA, the functional entities and interfaces that form IDA, and examples of IDA-compatible networks.
