A generalized stochastic Petri net model of Multibus II

Abstract

Results on the performance of a Multibus II based automation system are presented. These are achieved by means of a generalized stochastic Petri net model which was solved by analytical techniques instead of by simulation. The mapping of this industry-standard protocol to a stochastic Petri net model is outlined. It is shown how protocol features like arbitration priorities, parking, and message passing can be conveniently and efficiently analyzed from a Petri net model. This allows the estimation of optimum values for system parameters like the message size, and the identification of bottlenecks in a given architecture.<>
