摘要
A packet classification system, methods, and apparatus are provided for packet classification. A processor of a router coupled to a network compiles at least one search tree based on a rules set. The processor determines an x number of search phases needed to process an incoming key corresponding to the rules set, wherein the rules set includes a plurality of rules, where each of the plurality of rules includes an n number of rule fields and where the incoming key includes an n number of processing fields. The processor generates an x set of search trees, where each of the x set of search trees corresponds to a respective one of the x number of search phases. Also, the processor provides the x set of search trees to a search processor, where each of the x set of search trees is configured to process respective portions of the incoming key.
