摘要： 将元模型的思想应用于QoS管理，分析了定义QoS元模型所需的基本元素，研究了基于XML的元模型实现和应用方法，从而建立起开放的、可扩展的QoS表示体系。利用QoS表示体系，抽象出QoS空间、QoS水平及QoS状态的概念，在此基础上，结合模糊逻辑格运算，探讨了QoS适配管理的实现方式和具体算法。

Abstract: The paper introduces the metamodel idea into the domain of QoS management. It analyzes the basic elements for defining QoS metamodel and presents the ways to implement QoS metamodel using XML technology. Based on QoS metamodel, an open and extensible QoS specification system can be established and the concepts such as QoS space, QoS level and QoS state can be abstracted. The paper also discusses the algorithm and methods to implement QoS adaptation management based on QoS metamodel and fuzzy logic.
