Abstract: An example controller device that manages a plurality of network devices includes one or more processors implemented in circuitry and configured to: determine that configuration of one or more network devices of the plurality of network devices is to be updated; determine dependencies between types of resources provided by the network devices; construct a directed acyclic graph (DAG) representing the dependencies, the DAG having nodes representing the corresponding types of resources of the network devices of the plurality of network devices; sort the nodes of the DAG according to a grouped topological sort into a plurality of hierarchical levels according to the dependencies; and submit queries for two or more resources of the network devices at a common level of the plurality of hierarchical levels in parallel to determine resources of the determined types of resources of the two or more resources to configure the two or more network devices.

Abstract: A device may include one more processors to receive designed network information corresponding to a designed network; generate a data graph corresponding to a topology of the designed network based on the designed network information; receive discovered network information corresponding to discovered network devices of a discovered network; generate a query graph corresponding to the discovered network based on the discovered network information; perform a validation analysis of a topology of the discovered network relative to the topology of the designed network based on the data graph and the query graph; and/or perform an action based on a result of the validation analysis.
