基于GMA的分布式目录服务的设计与实现

A Design of Distributed Directory Service Based on GMA

网格监测已经成为网格正常运行的基础设施,目录服务对网格监测系统中的大量信息进行组织和管理。本文设计了一种基于网格监测体系结构GMA(Grid Monitoring Architecture)的分布式目录服务,内容包括体系结构、局部模块组成、存储的信息内容、数据传输格式和信息查询方式等。

Performance monitoring of distributed components is critical for enabling grid computing. Directory service has been used for organizing and making use of the data produced by grid monitoring systems. We propose a design of distributed directory service based on GMA (Grid Monitoring Architecture) that provides efficient and scalable discovery and queries of computing resources. In this paper,we present an overall architecture design of distributed directory service that enables quick response of user' s queries, as well as local components, information stored, data transmission format and query mechanism of local directory service.
