Recent progress in optical technology makes it possible to design innovative high speed network architectures. One possible architecture consists of a folded bus fiber in which parallel transmission channels are obtained using Wavelength Division Multiplexing (WDM). Nodes connected to the bus exchange data using the channels in parallel. Signals are transmitted from the source to the destination node in an all-optical fashion, thus avoiding the bottleneck of electronic processing at the intermediate nodes. The aim of the paper is to study the performance of the WDM bus network controlled by a novel access protocol proposed by the authors. The analysis is based on two GSPN models that allow to determine the access delay of the proposed protocol and its fairness throughout the nodes. As a result, it is possible to quantitatively determine the effect that some design choices have on system fairness. The paper discusses the strength and limits of GreatSPN, the tool used to perform the analysis.
