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.
Key words:
software rejuvenation,
