Abstract

Petri net models in which transitions can be associated with either deterministic or exponentially distributed firing times are developed to investigate the performance of a local area network with a linear topology in which a single bus is accessed by a finite population of stations randomly located along the bus using the 1-persistent CSMA/CD protocol. A detailed model is first constructed, mainly for specification purposes. Indeed, from such a model results can be obtained only through simulation. A compact, analytically tractable model is then developed, and it is validated by comparing its results with those obtained from the detailed model by simulation. Some performance curves show that the proposed compact model can be used to obtain accurate performance estimates in the considered case, which had previously been considered intractable.
