具有QoS保障的组合服务管理框架

Composite Service Management Framework for QoS Guarantee

在可信服务中间件架构的基础上设计了一种具有QoS保障的组合服务管理框架,在此框架下提出了QoS规划算法和服务选择算法.利用上层的重协商机制和下层的组合服务调度机制为服务提供双层的QoS保障,以最大化的满足用户的QoS需求.最后通过实验证明了框架和算法的有效性.

In this paper,a composite service management framework with QoS guarantee is presented,which is based on trustworthy service middleware architecture.In this framework,algorithms for QoS plan and service selection are presented.In addition,re-negotiation mechanism in upper layer and composite service scheduling mechanism in lower layer together provide two-layer QoS guarantee,which maximizes users′ QoS requirements.Finally the experiments ensure the validity of the proposed framework and corresponding algorithms.
