基于组合定权法的负载评价模型研究
Investigation on Load Evaluation Model with Combination Weighting Method
摘要
Abstract
With the rapid development of Internet technology and the geometric growth of massive data,the distributed storage and other related technologies are rapidly developed.The application of distributed file system has been a solutions for massive file storage and management.The current mainstream distributed file systems,such as Ceph,GlusterFS,MogileFS and so on,are widely used because of their own characteristics.Owing to the problem that the index of the load evaluation for open-source distributed file system FastDFS is single and impossible to reflect the real workload status of each server in real time,according to the research on existing load balancing technology,a multi-index based load evaluation model is proposed.It combines the subjective and objective factors and determines the weighting of each index by combination weighting method,so that the weight coefficient of the model can accurately reflect the real load of FastDFS under different application scenarios.The simulation results show that the proposed model is effective and feasible,which not only realizes the reasonable distribution of the load,but also improves the resource utilization rate of the system.关键词
