Accelerating the signature matching function is essential to perform Deep Packet Inspection (DPI) at line rates. The conversion of the signatures into the Deterministic Finite Automaton (DFA) enables performance of this function at linear time. However, since the DFA is extremely storage inefficient, it is compressed before being stored in the memory. This paper considers decompression approachesĀ to improve signature matching throughput.
