Abstract: A flexible and high-performance packet classification algorithm. The algorithm includes converting the original rule database into rule mapping table format for storage. The method of producing the rule mapping table includes partitioning an input key into a plurality of sub-keys, and sequentially comparing various grouping combinations of each sub-key with the same sub-key field of each rule. Finally, the results are stored in the rule mapping table using a bit-map method. This invention provides a packet classification algorithm that support a plurality of rule databases or sub-tables such that the co-existence of a plurality of rule databases each having a different length and width in the same search engine is permitted. In addition, the design can provide actual improvements (higher speed, smaller volume occupation) and flexibility (possible coexistent of different rule databases). Moreover, the search method can be used as a general-purpose search engine in the design of network processor or in any situation when rapid search is necessary. The search method can serve even as a replacement technology for CAM.
