摘要
对网络传输数据的存储负荷进行均衡管理,能够降低系统的存储负荷。网络传输数据存储负荷的均衡管理,需要选取电势最高源节点赋予存储空间,迁移数据进行重分配,完成数据存储负荷的均衡管理。传统方法先确定节点至存储位置间距离,设定存储阈值进行数据时隙分配,但忽略了重分配迁移数据,导致均衡管理效果不理想。提出基于最小化重分配策略的网络传输数据存储负荷均衡管理方法。调整数据重分配过程,以最小化重分配总负荷为目标构建目标函数。将势能函数引入目标函数转变最小跳数问题,数据项存储目的节点选取其相应电势最高的源节点赋予数据存储空间,源节点选取最近的许诺节点进行数据迁移,直至全部节点卸载溢出数据项为止,完成数据重分配过程,实现均衡管理。实验结果表明,所提方法进行网络传输数据存储,能降低系统存储负荷,节省存储开销。
The load balancing management of data storage in network transmission can,reduce the storage load of system.The traditional method ignores the redistribution of the migration data,leading to the unsatisfactory management effect.In this paper,we focus on a method of load balaneing management in network transmission based on the minimum redistribution strategy.Firstly,we adjusted the process of data redistribution.In order to minimize the total load of redistribution,the objective function was constructed.Then,the potential energy function was introduced to the objective function to transform the minimum hops.In addition,the source node with the highest electric potential is selected as the data storage space.Finally,the source node selected the nearest promised node for the data migration until all nodes unloaded the spillover data.Thus,we completed the data redistribution process and realized the balancing management.Simulation results show that the proposed method can reduce system storage load and save storage cost during the data storage in network transmission.
