SCALABLE LOOKAHEAD REGULAR EXPRESSION DETECTION SYSTEM FOR DEEP PACKET INSPECTION Regular expressions (RegExes) are widely used, yet their inherent complexity often limits the total number of RegExes that can be detected using a single chip for a reasonable throughput. This limit on the number of RegExes impairs the scalability of today’s RegEx detection systems. The scalability of existing schemes is generally limited by the traditional detection paradigm based on per-character-state processing and state transition detection. The main foc us of existing schemes is on opti-mizing the number of states and the required transitions, but not on optimizing the suboptimal character-based detection method. Furthermore, the potential benefi ts of allowing out-of-sequence detection, instead of detecting components of a RegEx in the order of appearance, have not been explored. Lastly, theexisting schemes do not provide ways to ad apt to the evolving RegExes. In this paper, we propose Lookahead Finite Automata (LaFA) to perform scalable RegEx detection. LaFA requires les smemory due to these three contributions: 1) providing specialized and optimized detection modules to increase resource utilization; 2) systematically reordering the RegEx detection sequence to reduce the number of concurrent operations;
