Grid And P2p Mixed-mode Resource Discovery Mechanism

The Grid is the third-time wave tide actually after traditional Internet and the world-wide-web, can call it is the third generation Internet. The resources share is a main characteristic of Grid, the resources discovers mechanism is a point research object in the Grid. Resources detection according to resources claim of the resources request a description, from the Grid for claim find out the process of suitable resources that satisfy description's request.In this paper, the study found that Grid resource efficiency based on the analysis of the traditional algorithms such as flooding and other shortcomings, the efficiency of resource discovery drawn the main reason is not a good mechanism for resource discovery, resource requests in the node transmission not the purpose of levy, resulting in a request in terms of resources covering a wide node, the resources have limited the growth response. In this paper, a hybrid structure of the P2P grid systems, in this mode of search resources is divided into regions and inter-domain search, and, respectively, for the region, inter-domain improve the search algorithm.Compare to the former resources discovers of mechanism, this thesis improves of searched calculate way to overcome a resources to check to seek of the blindness improves this mixture network mode to descend the efficiency and the credibility that the resources discovers a mechanism with random. The trust degree of node provided a guarantee for the safety, the node had the initiative the efficiency that the grade promised a resources a detection. Making use of the node has the initiative the area that the class computes certain node the place, the resources checks to seek from have the initiative the class high area to check to seek one by one in order, overcame the random of the resources detection, raised an efficiency. Moreover, thesisual mixture network mode, make the P2 Ps and Grid these 2 kinds combining the exploitation newly the distribute type calculation model, make their good and bad repair with each other, in expanding the function good foundation in the meantime benefit in management.
