【摘要】:針對服務計算中的服務可靠性,展開了對當前各種保證服務可靠性方法的研究.借鑒當前保證服務可靠性方法中所采用的關(guān)鍵技術(shù),并針對當前保證服務可靠性方法僅限于服務層面的不足,提出一種針對底層內(nèi)核模塊的可靠性技術(shù)—支持自恢復的微重啟技術(shù).同時,本文在嵌入式實時操作系統(tǒng)vxworks5.5版本中,針對內(nèi)核中的調(diào)度部分實現(xiàn)了支持自恢復的微重啟技術(shù),并采用相關(guān)故障注入技術(shù)檢驗了該技術(shù)的有效性.
[Abstract]:Aiming at the service reliability in service computing, various methods to ensure service reliability are studied. Draw lessons from the key technologies used in the current method of guaranteeing service reliability, and aim at the deficiency that the current method of guaranteeing service reliability is limited to the service level. A reliability technology for underlying kernel modules, micro restart technology supporting self-recovery, is proposed. At the same time, in the embedded real-time operating system vxworks5.5 version, the micro-restart technology supporting self-recovery is implemented for the scheduling part of the kernel, and the effectiveness of the technology is verified by using the related fault injection technology.
