An End-To-End Architectural Perspective of Broadband ISDN (2-11) (NOT PUBLISHED)

Broadband ISDN is natural evolution of today's narrowband ISDN, building upon the widespread deployment of fiber transmission systems and intelligent networks. It addresses the rapidly growing demands to make high bandwidths (100 of Mbps) available over both metropolitan and wide area networks in a cost effective manner. Indicative of these demands are the rapid growth of local area networks, high speed workstations, network fiber services, high resolution image transmission, supercomputer usage, etc. Broadband ISDN also introduces opportunities for new communications systems architectures and switching techniques that can serve voice, data, image and video requirements with common network switching and transmission fabrics. This paper describes the motivation for Broadband ISDN and how it may evolve to offer an end-to-end network architecture in response to evolving customer needs and technologies.
