基于动态阈值分配的流媒体边缘云会话迁移策略
Session Migration Strategy for Streaming Media Edge Cloud Based on Dynamic Threshold Allocation
摘要
Abstract
For the streaming media system based on the cloud model,more efficient and smooth resource scheduling is strongly required.In the traditional " last-minute migration ",only the load information is used for the migration scheduling.Due to the dynamic fluctuation of the video population,such indirect and single way cannot guarantee effective scheduling.Besides the load information,the video popularity is also used for the migration model,this paper propose a dynamic threshold allocated migration strategy.The allocation thresholds of different videos on each server are obtained on the basis of the new video popularity,and due to the guidance of the allocation threshold distribution,the blindness of request access and session migration can be avoided effectively.Experimental results show that the strategy cannot only effectively improve the request acceptance ratie,but also keep the migration cost low enough.关键词
