一种适用于分布对象环境的层次型故障检测方法的研究

针对现有故障检测服务在灵活性、伸缩性和扩展性方面的不足,提出了一种适用于分布对象环境的层次型故障检测方法.研究工作以两种通用概念模型(即故障提供者-监控者-使用者模型和域模型)为基础,指出了相关基本问题的解决途径.该方法引入了混合型故障监控模式,弥补了现有监控模式的不足;使用异步的消息传递机制,实现了故障信息的及时传播;采用基于域控制节点的层次型故障检测方法,解决了域内不同粒度实体故障检测问题.与同类研究相比,该方法在灵活性、伸缩性和扩展性方面具有一定的优势.

Research on an Hierarchy Fault Detection Method for Distributed Object-oriented Environment

Present fault detection services for distributed object-oriented environment have some deficiencies at flexibility,scalability and extensibility,thus a hierarchy fault detection method was presented.Two conceptual models,fault provider-monitor-user model and domain model,form the foundation of our method.Subsequently some solution ideas were proposed to resolve the related problems in fault detection.This method introduces hybrid monitoring mode to mend the deficiency of present mode,uses asynchronous messa...
