Embodiment Construction

[0042] As shown in Figure 1, it is a schematic structural diagram of the grid information service system of the present invention, and the system includes:

[0043] A management device 101 , a switching device 102 and an autonomous domain 103 . The autonomous domain 103 is a tree-structured network, and the root node 104 and other nodes 105 are Resource Locating & Description Service (RLDS for short) devices, which are called RLDS nodes and share the same information model and security policy. Provide grid users and grid applications with all kinds of information in the grid environment and manage the information effectively. Various types of information in the grid environment include: service information, including service type, interface definition, access address, etc.; static information and dynamic information of computing nodes, including computing node IP address, CPU type, storage capacity, real-time CPU Occupancy etc. Each RLDS node can have multiple child RLDS nod...

Abstract

The invention relates to a treatment method for successor node state information in a grid information service system with a tree-structure autonomous field as well as exchange device and management device, which comprises: successor node reports state information to father node; the latter decides state and cancels the successor node if failure. It also relates to an information query method in said system, which comprises: the node received query request first inquires local information whether meets request, if not, inquires in the sub-tree with this node as root; it not, continues to transmit query request to father node; if arriving root node of autonomous field, transmitting the request to other autonomous fields. This invention realizes to add resources into network conveniently, avoids information redundancy, has relative stable and robust structure, and improves information query efficiency in distributed structure.

Description

technical field [0001] The invention relates to an information service system and an information processing method thereof, in particular to an information service system applied in a grid environment, a method for processing sub-node state information of the system, and an information query method of the system. Background technique [0002] In the grid, resources are organized into different autonomous domains according to different affiliation relationships. The resources in the autonomous domains are relatively close in geographical distribution, the network overhead for mutual access is relatively small, and they have relatively consistent management strategies. When the grid scale is relatively small and the number of autonomous domains joining the grid is limited, a centralized information service structure can be adopted, that is, a global grid information service (Grid Information Service, GIS for short) is deployed to manage the information of various entities. Suc...
