一种基于服务质量的网格服务发现机制

Mechanism of service discovery based on quality of service in grid

网格服务体系结构的出现对网格服务发现提出了挑战,UDDI上基于关键词和简单分类的服务发现机制已经不能很好满足需要。本文在分析现有相关研究的基础上,提出了基于服务质量的网格服务发现机制,引入服务质量相似度的概念,为网格服务发现提供了一种有效可行的方法。

Grid Service Architecture challenges grid service, the service discovery mechanism in UDDI based on keywords and simple classification can not better meet the demand of the users. Based on analyzing current related researches, this paper puts forward grid service discovery mechanism based on QoS （Quality of Service） and proposes the concept of QoS similarity, providing an effective and feasible method for grid service discovery.
