流媒体集群系统中多目标复制存储方法
Multi-objective Replication Storage Method in Streaming Media Cluster System
摘要
Abstract
Based on the analysis of the distribution of popularity, session length, load balance degree and other {actors on system performance, a multi-objective replication and placement method in the streaming media cluster system is proposed. The problem of replica generation is summarized for the distribution of seats, and the optimal replication algorithm is proposed, which is heuristic to assign disk space for each replica of the streaming media replica to balance load, according to the characteristics of the file popularity of the Zipf-iike distribution. On this basis, the multi-objective evolutionary algorithm is used for global optimal replica placement. Simulation results show that the method in the case of the storage space is limited to lower rejection rate and a higher load balance degree.关键词
