Abstract :
In this paper, we investigate the performance and dependability modeling of voice and data services in computer networks. We use Stochastic Petri Net as an enabling modeling approach for analytical evaluation of complex scenarios. We apply our proposed modeling approach in a case study to evaluate the dependability of an enterprise network, in terms of Total Cost of Ownership, and to assess the financial impact of outages over voice and data networks. The performability will be analyzed by considering the influence of network topologies.
