Exact and approximate mean throughput models of the FDDI MAC-. Symmetric systems

The authors present an alternative method for computing the exact mean throughput of a symmetric FDDI network with both synchronous and asynchronous data streams. The approach they have taken is simple in that it only requires mean value estimates and can be computed readily. Closed form solutions for the exact mean throughput and token rotation times of a single priority symmetric network are derived. For networks with multiple priority classes, an iterative algorithm is presented which allows the same quantities to be computed. The approach also works for cases where the synchronous traffic stream is not saturated.<
