Delay analysis of the FDDI synchronous data class

摘要

An analytical model is applied to predict the performance of the FDDI (Fiber Distributed Data Interface) network in satisfying the delay constraints on the synchronous-class data frames. An example which illustrates the application of the analytic work and provides insight into the relationships between network performance and the negotiated parameter values of the FDDI protocol is given. In particular, the example demonstrates that while the current FDDI priority scheme guarantees a station will receive the token within a specified time, it does not guarantee that all waiting synchronous packets will meet their deadlines.
