R. Jain, "Performance Analysis of FDDI," Digital Technical Journal, Vol. 3, No. 3, Summer 1991, 18 pp.


The performance of an FDDI LAN depends upon configuration and workload parameters such as the extent of the ring, the number of stations on the ring, the number of stations that are waiting to transmit, and the frame size. In addition, one key parameter that network managers can control to improve performance is the target token rotation time (TTRT). Analytical modeling and simulation methods were used to investigate the effect of the TTRT on various performance metrics for different ring configurations. This analysis demonstrated that setting the TTRT at 8 milliseconds provides good performance over a wide range of configurations and workloads.
