摘要：A multi-layered fault injection mode is explored and a multi-layered system robustness testing strategy based on abnormal parameter is put forward. Fault injection methods for three layers (API, DPI and system calls based on workloads) of Linux operation system are designed. And an integrated fault injection platform to multi-layered fault injection for testing robustness of operating system is implemented. Using the multi-layered system robustness testing strategy based on abnormal parameter under the platform, various layers of system robustness evaluation are achieved. Finally, the results under different layers of fault injection are compared and analyzed in order to evaluate the robustness of target system.
