While string matching plays an important role in deep packet inspection applications, its software algorithms are insufficient to meet the demands of high-speed performance. Accordingly, the authors were motivated to propose fast and deterministic performance Root-Hashing Automaton Matching (RHAM) coprocessor for embedded network processor. Although automaton algorithms are robust with deterministic matching time, there is still plenty of room for improvement of their average-case performance. The proposed RHAM employs novel root-hashing technique to accelerate automaton matching.
