To resolve the SPIT hidden trouble in the ALL-IP fusion network,a multilayered detection method was proposed.First,the particular characteristic of SPIT behavior was analyzed deeply to enhance the pertinency of detection.Afterwards,multilayered mechanism was used to the detection.The signal monitoring algorithm can monitor all the SPIT-relevant unit information according to the particular characteristic of SPIT behavior.Statistical analysis algorithm adds up the unit information to gain the high-level semantic alert with statistiscal feature.Correlation analysis algorithm correlates the alert to gain the attack trace and reconstructs the attack scenario.Simulation and analysis show that the efficiency and performance of the method can satisfy the requirement of SPIT detection.
