Design of an enhanced FDDI-II system

It is pointed out that the growing demand for more bandwidth and integrated telecommunication services in the customer premises area can be satisfied with the hybrid high-speed local area network FDDI-II (fiber distributed data interface). A hardware design based on existing highly integrated components for the FDDI protocol is presented. The design contains all features according to the proposed FDDI-II standard. Additionally, the design provides features for enhanced performance, higher reliability, and extensive support for network management. The central component, i.e. the hybrid multiplexer (H-MUX), is described in detail. Implementation aspects of the station design and strategies of interconnecting the FDDI-II system to public networks, especially to integrated broadband communication networks (IBCN), are provided. Furthermore, the feasibility of current CMOS technology and design strategies for the high-performance requirements of this communication system are discussed
