本文扩展了服务抽象以支持服务质量属性，并在网格服务质量管理(G-QOSM)框架中加以实现。该框架支持三个主要功能：(1)提供通过服务等级协议(SLA)建立服务质量保证的机制；(2)支持对所分配的服务质量感知的服务进行服务质量管理；(3)支持基于服务质量属性的服务发现。该框架依赖于同时提供“功能”接口和“管理”接口的每个服务。功能接口提供关于如何调用服务以及它如何返回结果的属性，而管理接口用于提供与服务相关联的QOS属性和性能特征。本文的重点是实现一个基于服务质量的服务发现系统，该系统利用通用描述、发现和集成(UDDI)注册中心的扩展版本。
In this paper the service abstraction is extended to support quality of service (QoS) attributes - and implemented in the Grid QoS Management (G-QoSM) framework. The framework supports three main functions: (1) providing mechanisms for establishing QoS guarantees via service level agreements (SLAs), (2) enabling QoS management on allocated QoS-aware services, and (3) supporting discovery of services based on QoS attributes. The framework relies on each service offering both a "functional" interface and a "management" interface. The functional interface provides attributes on how a service is to be invoked and how it returns results, whereas the management interface is used to provide QoS attributes and performance characteristics associated with a service. The focus of this paper is on implementing a QoS-based service discovery system, which utilises an extended version of the universal description, discovery and integration (UDDI) registry.
