SLA驱动分布式业务管理的研究与实现

提出了Web服务的SLA(服务等级协定)与传统管理体系结构的资源度量之间的映射模式,建立了具有主动代理的业务管理模型.映射模式以WSLA定义SLA,基于公共信息模型(CIM)设计多种度量类型和进度计划,将复杂的SLA参数转换为业务提供者能够理解并且执行的资源度量.业务管理模型的资源子代理通过进度计划,能自觉请求检索新度量和计算SLA参数,无需外部客户触发,使模型的SLA监视和管理功能自动执行,有效地降低了系统开销.

Research and Implementation of SLA-Driven Distributed Service Management

A mapping schema between Web service SLA(service level agreement)and metrics based on traditional management architecture is proposed, and a service management model with active agent is also presented. The mapping schema defines SLA with WSLA (Web service level agreement) language, designs various metrics and schedules based on common information model (CIM), and maps arbitrarily complex SLA parameters into resource metrics that can be easily understood and enforced by the service provider. Through the schedules of the service management model, a resource subagent retrieves metric values from managed resources autonomously and calculates SLA parameters without replying on triggers by an external client so that assured services or SLA can be monitored and management automatically and the overall system resource consumption is reduced significantly. The simulation results have shown that the model can improve the management capability of distributed service.
