ABSTRACT
The Fiber Distributed Data Interface (FDDI) standard was produced by the ANSI X3T9.5 standards committee in mid-1980s and later approved by International Organization for Standardization (ISO) as an international standard. FDDI specifies a 100-Mbps, token-passing, dual-ring local-area network (LAN) using a fiber-optic transmission medium. High transmission speed and a bounded access time19 make FDDI very suitable for supporting real-time applications. Furthermore, the FDDI built-in support for fault-tolerant communication makes it possible to migrate mission-critical applications from large computers to networks. Several new civil and military networks have adopted FDDI as the backbone network.
