Abstract

Techniques have been developed to facilitate concurrent evaluation of hash rule entries in ways that allow an implementation to maintain a deterministic resultant hash irrespective of variations in the allocation of particular rules to particular storage banks or evaluation logic, such as may occur with rule set revisions. Similarly, uniform deterministic hash results can be assured even across a range of implementations that support greater or lesser levels of concurrent rule evaluations.
