Abstract
Grid is an effective pattern for implementing heterogeneous resource sharing.Information service is a vital component of grid system,it carries out efficient management of system services and resources.ChinaGrid is a large-scale grid containing multiple autonomous domains.Existing information services can not meet the requirements of systems and applications with such kind of characteristics.This paper presents GISA2.0(Grid Information Service Architecture,GISA),focusing on autonomous domain management and resource information security.GISA2.0 implements a scalable grid information model and service-oriented hierarchical information management framework,which supports the aggregation of monitoring information from multiple monitoring systems.To achieve secure,fast,and user-related virtual global resource view,GISA2.0 uses a cross-domain information retrieval mechanism based on distributed XPath engine.
