Abstract

The reliability of three fiber distributed data interface (FDDI) network topologies is examined. The three interconnection topologies considered are a tree, a double ring, and a ring of trees. The reliability measure is terminal-pair reliability in which the probability P[h(s,t)] that two arbitrarily positioned terminal stations (s and t) can communicate with each other is calculated. For the three FDDI network topologies considered, closed-form expressions are obtained for worst-case reliability as a function of the stations´ positions. The expressions are used to optimize the number of ports in and the topological interconnections of the wiring concentrators in order to achieve highest reliability for a given number of stations
