Network Performance Baselining

Chapter 10. Fiber Data Distributed Interface

The Fiber Data Distributed Interface (FDDI) network is a fault-redundant, point-to-point, high-speed LAN topology design. The FDDI network is based on a 100Mbps data-rate standard, although higher data rates can be achieved and are discussed later in this chapter. The design of a FDDI network is physically based on an infrastructure design that utilizes two physical rings. One ring is utilized as a primary ring; the second ring is utilized as a backup ring connection electrical link.

The nodes or stations that interconnect to a FDDI network can connect to either the primary or the backup ring at the same time, or just to the primary ring. The FDDI specification allows for approximately 500 stations to ...
