Abstract

A method, apparatus, and article of manufacture for performing compressed radix search tree lookups using transition tables. The key is used as a transition index into the transition table. A sum of transition bits in the transition table below the transition index is used as a result index into the result table. The result index into the result table may be used to reference a result of the radix search tree lookup.
