Intelligent Network Directions
Edward G. Sable, Herbert W. Kettler · AT&T Technical Journal · 1991
The main emphasis of the global products issue of the AT&T Technical Journal on intelligent networking is on the directions, platforms, and technologies needed to support the graceful introduction of intelligent networks (INs) by public switched telephone network (PSTN) providers. This paper introduces the objectives, principles, and attributes of IN, and offers a “roadmap” to AT&T's future IN architecture planning. The key attributes of IN architecture are service-independence, compatibility and synergy with existing networks, flexibility, and distributed intelligence. These qualities make it ideal for future network needs. We describe a scenario for an intelligent network built on standards, customer needs, and our experience with earlier versions of IN.
