Abstract: Focusing on the limited injection position and single target system problems existing in the simulation research of fault injection, combined with the NS2 simulation technology and fault injection method, an all-purpose simulation platform of fault injection was proposed. The layered model of the targeted information system was constructed, whose topology information and service performance information was given by the matrix, and improved the generality of the simulation platform of fault injection. Based on the configuration information, the platform constructed the fault library, which brought the cost reduction and reliability promotion of the system faults. The quadruple design of the fault configuration implemented the injection of any fault and reduced the configuration complexity. The simulation test results show that the simulation platform can simulate systems with any kind of requirements, and ensure the correctness and effectiveness of any fault injected at anytime and anywhere.
