Abstract
In a network element cache operation is enhanced by extracting a set of fields from a packet, constructing a hash key from the extracted fields, and identifying a subset of the fields, wherein the field values thereof fail to exist in a set of classification rules. The hash key by is modified by masking the subset of the extracted fields. A hash lookup is performed using the modified hash key in a cache memory that stores a portion of the classification rules. The packet is processed responsively to the lookup.
