Research on Minimum Cost Data Replica Distribution Based onDynamic Planning in Cloud Storage System
摘要
Abstract
Traditional replicas distribution strategies consider less data transmission cost and constrainsd network structure lack of universality,a minimum cost of replicas distribution strategy using dynamic planning technology is put up to minimize the overhead of data management in the cloud storage system.It presents a comprehensive data management model including data storage,transmission and the update cost,compares their values and chooses the one with lower cost for replica placement.Experimental results show that the strategy can realize reasonable distribution of replica from global minimum cost view,which can reduce the overall data management cost,and effectively reduce the network transmission and the average response time,and therefore promote the development of cloud storage system.关键词
