中文摘要: Web服务组合是动态网络环境下创建增值服务的新模式,蕴藏着巨大的应用价值,随着Web服务与云计算技术的成熟,组合服务的使用需求日益剧增。然而,服务集成商如何智能地处理不断到来的组合服务使用请求,在保证已有请求服务质量的同时提高服务资源的利用率是亟待解决的重大问题。本项目给出了面向组合服务的智能化接入控制解决方案,主要包括三个方面。首先,提出一种全局QoS约束自适应优化分解技术,将全局QoS约束合理地分解成每个服务类应满足的局部QoS约束,为接入判断提供重要的依据;其次,提出一种基于QoS动态预测和QoS干扰估计的可靠接入决策方法,提高接入判断的可靠性;最后,提出一种情景感知的服务资源自适应调度方法,根据接入请求时的情景为接入的请求分配最为合适的服务资源,从而提高服务资源的利用率。本研究将进一步揭示服务组合环境下接入控制的一般规律,为保证服务质量和提高资源利用率提供理论和方法支持。

英文摘要: Web service composition is a new model of creating value-added services under the dynamic network environment and contains great appication value, with the technology of Web services and cloud computing maturing, the demand of composite service grows sharply. However, service integrator how to deal with the continuous arrival of composite service use requests intelligently, and ensure the quality of the existing service requests while improving the resource utilization is a major issue for urgent solution. This project provides intelligent admission control for composite service,inluding mainly three aspects: Firstly, it proposes a global QoS constraints adaptive optimization decomposition technique which breaks global QoS constraints into local QoS constraints that service classes need to meet, this can provide important admission judgment basis; Secondly, it proposes a reliable admission decision-making method based on QoS dynamic prediction and QoS interference estimation to improve the reliability of admission judgment. Finally, in order to improve the utilization of the service resources, it provides a context-aware service resource adaptive shecduling method to allocate the most suitable resource to the new composite service use request. This study will further reveal the general rules of admission control
