针对数据网格中存储站点的容量限制,提出了一种基于权重的数据副本替换策略(WBRR).在网格模拟环境OptorSim上进行的模拟实验结果表明:基于权重的策略相比于传统的副本替换策略,在降低网络利用率的同时缩短了系统的响应时间,达到了提高系统性能的目的.
針對數據網格中存儲站點的容量限製,提齣瞭一種基于權重的數據副本替換策略(WBRR).在網格模擬環境OptorSim上進行的模擬實驗結果錶明:基于權重的策略相比于傳統的副本替換策略,在降低網絡利用率的同時縮短瞭繫統的響應時間,達到瞭提高繫統性能的目的.

For adapting to the limitation of storage capacity in data girds,a weight-based replica replacement strategy(WBRR)is presented in this paper.Results from the simulation procedure in OptorSim show that the effective network usage and the mean time of jobs of WBRR is lower than the ones of traditional algorithms,and WBRR can obtain better performance for data grids.
