Modelling Role-Playing Games Using PEPA Nets

We present a performance modelling case study of a distributed multi-player game expressed in the PEPA nets modelling language. The case study provides a modern complex distributed application programming problem which has many inherent communication and synchronisation complexities which are subtle to model accurately. We put forward the position that a high-level performance modelling language is well-suited to such a task. The structure of the model and the performance index which is most significant for the problem match well a solution method which has previously been applied in Petri net modelling. We apply this method to a PEPA net model for the first time in this paper.
