Description	Modern computer networks are complex and their topology can dynamically change when links go down. It is difficult to predict behaviour of a large network with dynamic routing protocols. To automatically prove survivability and reliability of an end-to-end connection, formal analysis combined with simulation can be exploited. In this paper, an approach based on detection of critical elements using formal analysis and subsequent simulation of time related properties is introduced. Our network model is based on graph theory and is automatically extracted from configurations of network devices. Then, critical network elements are detected using graph search algorithms. In addition to graph analysis, several simulation scenarios are executed over the model in order to detect time dependencies. Modeling and simulation is done in OMNeT++ simulator, formal analysis is computed using scripting. The first results of this combined analysis show feasability of this approach and help to reveal both q Modern computer networks are complex and their topology can dynamically change when links go down.
