Abstract: One aspect of the instant application facilitates automatic policy engine selection. During operation, a system can monitor a network including a set of network devices. The system can receive, based on the monitoring, a set of attributes associated with the network. At least two network devices are equipped with a different policy enforcement engine for enforcing one or more given policy rules. The system can apply a unified policy model to determine, based on the set of attributes, an assignment of the one or more given policy rules to the first policy enforcement engine and the second policy enforcement engine for providing an optimized policy enforcement. The system may then select based on the assignment, one or both of the first policy enforcement engine and the second policy enforcement engine. The system may activate the selected one or both policy enforcement engines for enforcing the given policy rules.

Abstract: One aspect described in this application provides a unified policy broker. During operation, the system receives configuration information from the set of network devices. At least two network devices in the network can be equipped with a first and a second policy enforcement engine, respectively, for enforcing one or more given policy rules. The system can determine, based on the configuration information, a first and a second representation of the similar policy function corresponding to the first and the second policy enforcement engine, respectively. The system can apply a unified policy model to perform a first mapping from a unified representation of the similar policy function to the first and the second representation. The system can create a unified API based on the unified representation. The system applies, via a user interface, the unified API to configure the similar policy function across the first and the second policy enforcement engines.
