Global intelligent networking: architectures, services and design principles

This article focuses on the driving needs, key attributes, design principles, design target and constraints of an intelligent global infrastructure as global carriers all move rapidly toward seamless services deployment. First, this article reviews the needs for and the driving forces behind a global intelligent infrastructure. Second, the attributes or key characteristics of a global information superhighway, along with its potential applications, are postulated. The AT&T Worldwide Intelligent Network is illustrated as an application example. Finally, the guiding principles, design targets and design constraints frequently utilized by network architects and system designers are presented. Some presentation materials or viewgraphs are illustrated
