摘　　要：针对服务计算中的服务可靠性,展开了对当前各种保证服务可靠性方法的研究.借鉴当前保证服务可靠性方法中所采用的关键技术,并针对当前保证服务可靠性方法仅限于服务层面的不足,提出一种针对底层内核模块的可靠性技术—支持自恢复的微重启技术.同时,本文在嵌入式实时操作系统vxworks5.5版本中,针对内核中的调度部分实现了支持自恢复的微重启技术,并采用相关故障注入技术检验了该技术的有效性.As to the service reliability in service computing,this paper launches a research on current methods of guaranteeing service reliability.This paper uses some critical technologies adopted by current guaranteeing service reliability methods for reference,and puts forward a kind of technology on guaranteeing the reliability of underlying kernel modules——micro-reboot technology with supporting self-healing,looking at the insufficiency that current guaranteeing service reliability methods are just realized on the service layer.Besides,this paper has realized the above micro-reboot technology with supporting self-healing on the scheduling part of embedded real-time operating system vxworks5.5 version,and has taken some related fault injection technologies to verify the effectiveness of this technology.
