摘要
副本定位技术是数据网格的关键技术。本文采用改进的Chord算法,同时借鉴了结构化P2P技术,提出了一种基于结构化P2P模式的副本定位方法。该方法能在一定程度上解决局域网间的"绕路"问题,提高了定位效率,节省了传输时间和带宽,优化了数据网格的性能。
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.
