An approach and a tool for IP network state-to-state transformation

Abstract— The article presents an approach and a tool for network state-to-state transformation. Each network has a state. The state could be formalized into an architectural graph data model that contains network nodes, edges and key metadata. The state-to-state transformation happens as a chain of evolution steps from the initial to the desired network state. Each step has technical and business constraints, an action and leads to a desired effect. The steps could be combined in strategies. The strategies could be formally evaluated through the algorithm for multi-criteria analysis based on the business constraints associated with the containing steps. The successor strategy is called an “evolution path” and is the one that will be used to evolve the network. The approach has been fulfilled through a software tool able to discover the network state, to upload it in a graph data model, to change it and to perform a rediscovery finally to visualize the differences between the two network states.
