Grid Information Service Architecture in ChinaGrid

Grid information service, a key component of grid, implements the management of grid system and its resources. This paper presents Grid Information Service Architecture (GISA2.0) that developed for ChinaGrid Support Platform (CGSP2.0). GISA2.0 is a service-oriented hierarchy management model, which supports unified management of all grid resources. It implements a hierarchical monitoring model, which collects information effectively with low system intrusion and discovery of state change in time. Domain autonomy and grid information security are emphasized, and secure global information sharing is achieved with a standard domain exchange mechanism
