Abstract

In the simulation based design and development of Service Based Software Systems (SBS), it is important to analyze the models for correctness and improve confidence in the validity of the model. Of particular interest is the SBS simulation where models are used towards evaluation of time dependent QoS metrics (e.g., service delay, throughput etc.). In this paper, an experiment based validation of Service Based Software Systems using SOC-DEVS (i.e. Service Oriented Computing DEVS) framework is presented. As formal basis towards validation, the real system under consideration is abstracted as a DEVS I/O System model and experiments are developed to observe its time-based I/O trajectories. An exemplar Voice Communication System is simulated and results are analyzed towards model validation w.r.t. a real system prototype.
