Abstract
A method and corresponding apparatus are provided implementing run time processing using Deterministic Finite Automata (DFA) and Non-Deterministic Finite Automata (NFA) to find the existence of a pattern in a payload. A subpattern may be selected from each pattern in a set of one or more regular expression patterns based on at least one heuristic and a unified deterministic finite automata (DFA) may be generated using the subpatterns selected from all patterns in the set, and at least one non-deterministic finite automata (NFA) may be generated for at least one pattern in the set, optimizing run time performance of the run time processing.
