Digital Technical Journal

This journal issue provides a comprehensive overview of the Fiber Distributed Data Interface (FDDI) technology as implemented by Digital Equipment Corporation. It includes technical papers detailing the physical layer development, data link development, the creation of common node software (CNS) for interoperability and management, and the design and development of specific FDDI products such as the DECbridge 500 and DECconcentrator 500. The articles cover design challenges, performance considerations, standards compliance, and the development methodologies, including simulation and verification processes, used to bring these 100-megabit-per-second LAN systems to market.
