Resource Utilization In Grid Environment With Peer-to-Peer Network Technology

Recently, Grid and P2P computing are the reaching hotspots in the distributed computing field. As a new network technology followed Internet and Word Wide Web, Grid tries to carry out the connectedness of all the resources in the Internet. And it wants to make the resources integral as a super server. Then forming a virtual high-powered environment which is translucent for users is ultimately to carry out the resources sharing and co-working in the virtual web. But the basic theory of P2P is that the peer of web can not just get the resource or service from other peers, but also supply the resource or service to the others. It means that peer has the functions of C/S. So P2P is a resource managing model which is dispersive and distributed.Though Grid and P2P computing use the different technology, they also have the same target which is sharing and co-distribute the resources of hard wares and soft wares. So recently, there is a trend that Grid and P2P will inosculate. In fact, Grid is still in the primary stage. It has several problems, such as service will be the bottleneck of the system because of that Grid needs center service to answer for the searching an co-working of resources in nowadays. And because accessing resources in Grid is related with strict accounting rules, it will appear a problem that is the invalidation of nodes. Also it is forbidden that user is anonymity in Grid safety rules, which will restrict the size of Grid.The article researches a system where Grid is combining with P2P in a uniform resource sharing circumstances, and exploits a Grid application which can access and coordinate remote resource and service. The architecture is a Grid system which adopts P2P resource searching ways in the under layer such as QBVT, Grouping to solve over loading and lower resource searching efficiency problems constructs a Grid platform in the upper layer to satisfy different accessing needs. The Grid combining with P2P is a non-centralization architecture, in which sharing resources will be accessed directly by nodes without passing the middle server. It can improve the C/S architecture defect in the Grid and enhance the expansibility, safety and reliability of the system.
