Abstract: Systems for and methods of modelling, analyzing and managing data networks are provided. In an embodiment, a plurality of network device interfaces are configured to collect state information for a plurality of network devices. A computer-implemented model of the network comprises a data structure, which may be graph-based. The data structure comprises a plurality of snapshots of the network, each snapshot representing the network at a particular point in time, and the data structure comprises a representation of possible data flow and data packet processing within the network. The data structure contains normalized representations of the network devices corresponding to the location. The normalized representation for each device contains a set of packet processing rules. A user-interface is configured to receive queries from a user that request verification of network policies and predictions of network behavior. The user-interface is configured to display responses to the queries that are obtained using the data structure.
