A Method of Locating Data Grid Replica Based on the Structured P2P Scheme

Replica locating is one of the most important key techniques in data grids. This paper adopts an improved chord algorithm and refers to the structured P2P technology, and then proposes a method of replica locating in data grids based on the structured P2P scheme. In this way, it can solve the "detour" problem to a certain extent, improve the efficiency of locating, save the transfer time and bandwidth, and consequentally optimize the performance of data grids.
