摘　　要：针对故障注入仿真研究注入位置受限、平台单一等问题,结合NS2仿真平台和故障注入技术,提出故障注入通用仿真平台设计方案。该方案为系统建立层次结构模型,并以矩阵形式提供拓扑和服务能力信息,提高了故障注入仿真平台的通用性;基于系统配置信息构建故障库,降低了系统故障分析成本,并提高了故障来源的可靠性;设计四元组配置格式实现任意组合故障的注入,降低了故障注入配置的复杂性。仿真实验结果表明,基于该方案构建的仿真平台能够实现满足任意需求的目标系统仿真,并能够保证任意时间任意位置注入故障的正确性和有效性。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.
