Design of the ISO class 0 transport protocol: a stepwise refinement based approach

We present the design steps of the ISO Class 0 transport protocol. We apply, for this purpose our protocol synthesis algorithm. This algorithm is based on stepwise refinement of specifications written in an interpreted Petri net model. The starting point for the design is the specification of the ISO transport service. The main advantage of this design strategy is that the correctness of the designed protocol is guaranteed.
