Evolution of the local switched network

Abstract

The major directions for the multidimensional evolution of the local switched network are discussed together with the forces behind these changes. These directions fit within three themes: improved network operations, increased bandwidth, and service flexibility. It is projected that network operations efficiency will improve, especially in the area of ISDN (integrated services digital network) OAM&P (operations, administration, maintenance, and provisioning). Bandwidth capabilities in switching and transmission will expand through MANs (metropolitan area networks), BISDN (broadband ISDN) and 1.5 Mb/s switched services. Flexibility will increase for service customization and vendor selection. The intelligent network will restructure the positioning of service control to permit more rapid feature introduction. In a cooperative effort, vendors and network providers will form industry standards that will provide the directions for this evolution.<>
