In this thesis, the performance of the fiber distributed data interface (FDDI) local area network is evaluated by software simulation. The network is modeled with OPNET, a communication network simulation tool. The main focus of the model is on the medium access control (MAC) and the timing requirements that need to be met for the correct behavior of the protocol. Simulation data is presented to support results from previous analytic studies of distinctive features of the protocol, including the behavior of the token rotation time, synchronous frame delays, fairness of channel access for nodes transmitting asynchronous traffic, etc. Comparisons between the simulated and theoretical results confirm the accuracy of the OPNET simulation tools and demonstrate that it may be used to model other protocols of particular interest.
