一种改进的XFA在深度包检测中的应用
Improved XFA for deep packet inspection
摘要
Abstract
An improved XFA for deep packet inspection is proposed. Firstly the branching transitions are augmented with the check instruction and the backward transitions are eliminated; then the parallel detection mechanism is used, the original thread is replaced by the two parallel threads which are in order to accelerate the speed of matching : the pre statistical thread and the state machine matching thread. The experiments show the algorithm has a faster speed and stability, and is suitable for multi-core computing environments.关键词
