Abstract
In one embodiment, a super class that contains a plurality of matching rules is generated. The matching rules of the super class are converted into a hierarchical arrangement of lookup tables and equivalence sets, the hierarchical arrangement having a plurality of levels including a first level and a final level. A final equivalence set is associated with the final level. The lookup tables and final equivalence set are then used to generate a results table that indicates a network packet is associated with a particular class.
