中文摘要: 云计算是信息技术发展和信息社会需求到达一定阶段的必然结果,是一种全新的技术手段和计算模式。本研究以云服务、网络服务和通信服务为对象,以QoS保障为主线,提出"云服务与网络服务一体化环境下的QoS保障机制研究"课题。课题以综合提高云计算环境下服务区分接入与调度的公平性、服务组合的有效性和网络服务性能的可靠性三个关键特性为目标,以QoS保障体系建模研究为切入点,以"建模(Modeling)- - 优化(Optimization)- - 分析(Analysis)"的过程化递进为手段,系统研究云服务与网络服务一体化环境下的QoS保障模型,探索一体化环境下服务区分与调度机理,提出一体化环境下的服务组合方法,建立一体化环境下的QoS测评体系,为提高我国云计算的整体服务质量水平提供理论和使能技术支撑。

英文摘要: With the development of IT technology, Cloud computing is emerged as a new computing paradigm that provides services to the end users. In the Cloud computing system, network performance usually has a great impact on the Cloud service provisioning performance. This research presents two notions, namely CaaS (Communication-as-a-Service) and NaaS (Network-as-a-Service) in the composite Network-Cloud context, and invesitigates its QoS machenisms. Based on above notions, the research then gives an end-to-end QoS-aware service provisioning model, explores the service admission control and scheduling machenisms, proposes several service composition algorithms, and estabilish an evaluation system for composite Network-Service provisioning in order to imporve the fairness of service diffirentiation and scheduling, effectiveness of service composition, and reliabilty of serving network. The research is expected to provides theoretical references for improving the entire serving quality of Cloud computing in our country.
