一种可扩展的soa服务质量描述模型

面向服务的架构已经成为软件产品开发和企业信息系统建设的主要技术和方法。随着具有相同或相似功能的服务日益增多，人们对于服务质量的关注随之增强。通过对SOA服务质量属性特征、特征的分类、QoS模型的现状进行研究，分析了SOA的服务质量研究面临的问题，并针对QoS的特点提出了一个QoS描述模型，该模型反映了SOA服务质量的多侧面、动态性的特点，支持灵活扩展和动态度量。

Extensible Model for SOA Quality of Service

Service-Oriented Architecture(SOA) is emerging as a prevalent technology for software and enterprise information system development. As more and more services with similar functionality, people pay increasingly attention to Quality of Scrvice(QoS). This paper made the state of the art analysis to QoS models, and classified characteristics in existing literature. Their advantages and disadvantages were summarized. This contribution presented a QoS model for SOA which reflects its multi dimensional characteristics, and can be extended and measured dynamically.
