Optimizing Regular Expression Engines for High‑Performance Deep Packet Inspection
This article presents a series of algorithmic innovations—including efficient NFA construction, reduced epsilon‑transitions, prefix/suffix optimizations, fast NFA‑to‑DFA conversion, space‑compressed automata, hybrid finite automata, and large‑scale regex matching techniques—designed to improve regular‑expression matching speed and memory usage in deep packet inspection systems.
