Abstract
Instances of router models and filter models respectively are populated with configuration data from routers and filters in a network. A route advertising graph is derived from the router model instances. The route advertising graph indicates propagation of routes between the ones of the real-world devices serving as routers according to routing protocols implemented by the ones of the real-world devices serving as routers. Consolidated routing data is determined for the ones of the real-world devices serving as routers. In this process, the propagation of routes indicated by the route advertising graph is iterated to stability. For a destination node in the network, a respective route graph indicating available paths to the destination node from each source node in the network is constructed from the consolidated routing data. Services between each source node and the destination node are classified based on a full traversal of the route advertising graph.
