摘要/Abstract

摘要： 针对云服务的冗余特性和可靠性保障的需求,探讨了提高云服务可靠性的有效途径。基于云服务的可靠性体系框架和管理模式,提出了信任冗余的云服务可靠性增强总体框架；在服务准备时的冗余设计阶段,基于选举协议的云服务轮询检测机制,设计了信任感知的容错服务选择算法,给出了最小容错服务个数的求解方法；基于服务组合运行时的容错处理框架,提出了保证服务响应时间的基于失效规则的云服务调用策略。实验结果表明,提出的容错服务选择算法和云服务调用策略具有较好的实用性和有效性。

关键词: 云服务,可靠性设计,信任冗余,失效规则

Abstract: In allusion to the redundant features and reliability guarantee requirements,this thesis tried to explore the effective ways for improving cloud service reliability．A trust redundancy reliability enhancement framework of cloud ser-vice was put forward based on the reliability architectue and management model．On the redundant design phase of the service being ready,based on the failure polling detection algorithm of voting protocol,a trust-aware fault-tolerant ser-vice selection algorithm was designed,and the calculation methods of min-number of fault-tolerant services were given．Based on the running fault-tolerant management framework of services combination,a cloud service invoking policy of ensuring service response time based on failure rules was presented．Experiments show that the fault-tolerant service selection algorithm and the cloud service invoking police have more practicality and effctiventness.

Key words: Cloud service,Reliability design,Trust redundancy,Failure rule
