摘要:

PoSOA系统是针对电力系统信息服务需求开发的基于面向服务的架构(SOA)的一站式电力综合信息服务系统。系统中的服务来自不同的提供者,难免存在很多功能相似、服务指标(响应时间、可用时间、造价等)各异的服务,给服务的选取和替换带来难度。以PoSOA系统的具体需求为牵引,提出了一种服务质量(QoS)属性描述模型,以支持不同应用系统中与问题域相关的QoS属性描述集合的定制,支撑面向服务应用中的服务选取及异常处理。该描述模型在电力应用系统中得到了应用。

Abstract:

According to service need of electric power information, PoSOA is developed as a onestop integrated information service system based on serviceoriented architecture (SOA).Inevitably, there are varied services with similar functions and service indicators (response time, available time, cost, etc.), since they are from different provides. This makes services selection and replacement difficult. Driven by the requirements of PoSOA, it presents a QoS property description model that helps to customize the description set of QoS properties with relevant problem domain for different applications, and provide better supports to service selection and exception handling in serviceoriented applications. The model has been applied in power application system.
