A processor of a security appliance coupled to a network uses a classifier table having a plurality of rules, the plurality of rules having at least one field, to build a decision tree structure including a plurality of nodes, the plurality of nodes including a subset of the plurality of rules. The plurality of nodes may be stride nodes, mask nodes, or a combination thereof. A mask node may remove restrictions of stride nodes, such as markers and consumption of contiguous bits. As long as a bit of a field is a non-consumed bit, the bit may be used for cutting a field in a mask node. An advantage of a mask node is that the mask node may consume fewer resources (e.g., memory) than a stride node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Compiler with mask nodes","description":"A packet classification system, methods, and corresponding apparatus are provided for enabling packet classification.
