Abstract

Recently, several researches have suggested an application of formal methods for identifying configuration errors, unveiling design problems and predicting network behavior. In this paper, we contribute to this research area by defining a method able to efficiently check reachability properties in dynamically routed networks. We define a notion of network state that captures different network conditions. Each network state represents a unique combination of link availability. The naive enumeration of network states leads quickly to intractability even for small networks as the number of possible combinations grows exponentially. Instead, we enumerate all available paths and, for each path, we search for state aggregation, in which this path is active.
