| 摘 要： | 将软件抗衰粒度细化到组件级，执行嵌套的抗衰重启策略，可以降低抗衰成本，提高软件可靠性。该文根据软件系统中组件间控制、调用及数据访问的关系，确定了寻找直接耦合组件的途径和系统组件重启树生成方法，构建嵌套的组件级抗衰重启策略，并为系统细粒度软件抗衰提供支持。

| Abstract: | In order to save costs of software rejuvenation and improve software availability and reliability, rejuvenation granularity is improved to the component-level and the nested software rejuvenation policy is executed. Based on coupling relation among components of the software systems, this paper puts forward a method to search the direct coupled processes, sets down the rule of building component restart tree of system, and establishes the nested software rejuvenation policy on component-level. It supports to execute software rejuvenation with fine rejuvenation granularity. |
