In this article, WEB Services, 5-layered hourglass model and the Open Grid Service Architecture (OGSA) are analyzed and compared, the focus of which is on the exact analysis of the components, interfaces and soft-state lifecycle management of GT3.Based on the analyses of the classification, the memory and the services of the grid information, the Information Monitoring and Discovery System (MDS) of the GT3 and the GT4 are discussed respectively. The index service of the GT3 is studied in detail.Use the Broken line-index model to find the grid resource, based on the analyses of the getting of the resource information. First, start the index service machine. Second, start the Grid Service resource and register its information into the index service machine. Finally, users use the client programme to look for the resource from the index service machine, find out the physical characteristics of the resource, and locate the first satisfactory grid resource. To test the function of the model, simulation is made, indicating that the model can completely satisfy the demand on the discovery of resources in the local net.Finally, it is detailed how to build grid installing GT3, how to deploy services into GT3.
