Analysis And Research About Topology Optimization And Resource Location In P2P Network

The problem of resource location is still an open question in current P2P network; the application about location methods should be designed for specific performance in specific environment. Of course, the performance analysis of various positioning methods has very good reference for the design better positioning method in actual application. This article is mainly analysis and optimization on the P2P network resource locator methods.Unstructured P2P network resource locator search is mainly based on the flooding search, which will engender a lot of redundant data packets. In this paper, we put forward the Condensing Forward-List algorithm (CFL) to reduce redundancy. Through the simulation experiments we find that the CFL algorithm has higher performance compared with the flooding algorithm. The resource locator in structured P2P network has the suppout of higher efficient routing algorithm; however, structured P2P networks do not support fuzzy queries, the amount of inquired information does not achieve the user requiements. In order to positioning resouces effitiently but not having too much redundancy, a sub-domain hybrid P2P model is proposed in this paper. We give a detailed analysis about the design idea of the model.That hybrid P2P model makes full use of the advantages of the unstructured and structured P2P networks, as far as possible to avoid the inadequacies of their. On the realization of the model, there is a detailed introduction in this paper.We design our algorithm to be simple, as a module that can be easily applied to existing P2P systems for immediate impact. This paper is based on improving the efficiency of P2P network resource locator. The theoretical conclutions of this paper can be a reference provided to the developers.
