A processor of a routing appliance coupled to a network compiles data structures to process keys associated with a particular block mask register (BMR) of a plurality of BMRs. For each BMR of the plurality of BMRs, the processor identifies at least one of or a combination of: i) at least a portion of a field of a plurality of rules and ii) a subset of fields of the plurality of fields to be masked. The processor also builds at least one data structure used to traverse a plurality of rules based on the identified at least one of or a combination of: i) at least a portion of a field of a plurality of rules and ii) a subset of fields of the plurality of fields to be masked."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Block mask register key processing by compiling data structures to traverse rules and creating a new rule set","description":"A packet classification system, methods, and corresponding apparatus are provided for enabling packet classification.
