摘要：A fast policy classification method and system. A policy differentiator can be
provided which can include a policy repository configured to store hierarchical policyclassification trees. The policy differentiator further can include a hashing moduleconfigured to produce integer values for string based selector attributes. In one aspectof the invention, the hashing module can include a longest string hashing function. Apolicy matching engine can be provided which is configured to locate policy rules in thehierarchical policy classification trees according to the integer values produced for thestring based selector attributes. Finally, a policy matching engine interface can beprovided through which policy queries and resulting policy decisions of the policymatching engine can be communicated between the policy matching engine and thepolicy enforcement entity.
