摘要:

已有的架构风格可靠性研究主要针对单一软件架构风格，为研究软件部署阶段的多种架构风格的 系统可靠性，设计用连接器的方式来建模部署阶段的集成架构风格系统和软件组件可靠性．实验结果表明， 随着系统运行时间的增加，集成架构风格的系统可靠性和组件可靠性主要依赖于处于执行状态的软件组件 数目和软件组件处于执行状态的时间．通过对集成架构风格系统可靠性和软件组件可靠性的分析，有利于选 择合适的时间通过系统重部署或者软件组件复制来提高系统可靠性

Abstract:

Existed reliability researches of architectural styles are mainly aimed at individual architecturalstyle. To study system reliability of multiple architectural styles during software deployment stage, the systemof integrated architectural style and reliabilities of software components are modeled by the connector method.Experiments show that with the increasing of system run time, the system reliability of the integrated architec-tural style and component reliabilities mainly depend on the number and time of software components which arein the executed state. On the basis of system reliability analysis of the integrated architectural style and relia-bilities of software components, the reasonable time is decided by redeployment or replicating components toimprove the system

Key words:  architectural style  reliability  software deployment  software architecture
