Error Characteristics of Fiber Distributed Data Interface (FDDI)

Fiber Distributed Data Interface (FDDI) is a 100 megabits per second fiber optic local area network (LAN) standard being developed by the American National Standard Institute (ANSI). We analyze the impact of various design decisions on the error detection capability of the protocol. In particular, we quantify frame error rate, token loss rate, and undetected error rate. Several characteristics of the 32-bit frame check sequence (FCS) polynomial, which is also used in IEEE 802 LAN protocols, are discussed.
