摘要： 介绍了S-Club原理，分析了已有实现方法的不足，提出一个适合在网格信息服务系统中实现S-Club机制的设计方案，包括如何创建、维护和撤销S-Club以及如何在S-Club中进行查询。利用该套设计方案，在CROWN信息服务系统RLDS中成功实现了S-Club机制，通过实验证明了S-Club机制确实能够提高信息服务系统的查询效率，减少综合网络开销。

Abstract: This paper introduces the S-Club mechanism and analyzes the deficiency of the original implementation method. It proposes a framework appropriate for applying S-Club mechanism in grid information service, which includes the procedure of creating, maintaining, destroying an S-Club and the query in an S-Club. According to the framework, S-Club mechanism is successfully implemented in the RLDS, the grid information service in CROWN Grid. Experiments show that with the introduction of the S-Club, query efficiency of RLDS is promoted significantly, and the overall cost of communication is reduced as well.
