The Connect project targets at enabling seamless communication among heterogeneous networked systems. Veri cation and Validation (V&V) ensure Connected systems to satisfy dependability requirements. Stochastic model checking and state-based stochastic method are two appealing V&V approaches to accomplish the task. In this paper, we demonstrate the application of two approaches in Con- nect settings by analysing dependability properties for a typical scenario of Connected systems. Not only will we show that a set of basic properties can be cross-validated by both approaches, but also we check additional properties, which can only be handled easily by one of the approaches, to investigate relative strengths and weakness of each approach.
