A traffic policy includes policy rules that specify branch actions in their action fields. A branch action specifies another policy rule in the traffic policy. Packet filters generated from the traffic policy represent the traffic policy rules and execution order semantics of the branch rules.

Embodiments of the present disclosure include systems and methods for updating packet processing rules of network devices. A request to update a first set of rules stored in the memory with a second set of rules is received. Upon determining the update from the first set of rules to the second set of rules satisfies a defined condition, the first set of rules in the memory is updated with the second set of rules. Upon determining the update from the first set of rules to the second set of rules does not satisfy the defined condition, the update from the first set of rules to the second set of rules is decomposed into a first set of operations and a second set of operations and the first set of rules in the memory are updated with the second set of rules.

Staging in-place updates of packet processing rules of network devices to eliminate packet leaks

A computer-implemented method for generating a ternary content addressable memory (TCAM) profile includes obtaining an access control list (ACL) configuration and generating the TCAM profile by parsing the ACL configuration. Based upon the parsing, one or more configuration features are identified, each of the features based upon a context and direction of packet flow identified in the configuration. The context includes an interface type and a routing configuration type. Based upon identifying each of the one or more configuration features, a corresponding feature is generated in the TCAM profile. At least one qualifier and at least one action associated with the respective feature is identified and associated with the feature in the TCAM profile.
