Abstract: Example method includes: negotiating, by a network device, a location of a data source for a particular network infrastructure manager; inferring, by the network device, a meta label namespace by analyzing the data source, wherein the meta label namespaces comprises at least a relationship between a plurality of meta labels; inferring, by the network device, a label namespace that is specific to the particular network infrastructure manager from the meta label namespace; converting, by the network device, the label namespace to an abstract label namespace; and aggregating, by the network device, the abstract label namespace into a global label namespace that is applicable across diverse network infrastructures.

Abstract: Example method includes: receiving, by a network device in a network, a first network policy and a second network policy configured by a network administrator, wherein the first network policy comprises a first metric and the second network policy comprises a second and different metric; detecting, by the network device, a conflict between the first network policy and the second network policy; determining, by the network device, a relationship between the first metric and the second metric; modifying, by the network device, at least one of the first network policy and the second network policy to resolve the conflict based on the relationship between the first metric and the second metric; and combining, by the network device, the first network policy and the second network policy to generate a composite network policy that is represented on a single policy graph.

Abstract: A method for verifying network intents may include decomposing at least one network intent into a plurality of sub-verification tasks, generating a set of normalized configurations for a plurality of network devices in a target network based on a set of current configurations for the plurality of network devices and generating a network graph based on the set of normalized configurations and a topology of the target network. The method may further include analyzing the plurality of sub-verification tasks and the network graph to determine if the set of current configurations for the plurality of network devices satisfies the at least one network intent. If the at least one network intent is not satisfied, a report may be generated indicating that the target network is not in compliance. If the at least one network intent is satisfied, information may be provided indicating that target network is in compliance.
