混合流媒体分发系统中多指标用户群分组算法
A User-group Grouping Algorithm Based on Multiple Indicators in Hybrid Streaming System
摘要
Abstract
To address the problem of additional cross-regional and cross-network cost that appears when the service node provides streaming media services,and the problem of inefficiency in searching service node,a grouping algorithm based on multiple indicators is proposed and used in server selection. As the algorithm goes,the user-group would be grouped by the node location and network type successively,limited the candidate server nodes in the same area and the same ISP,consequently reduced additional cross-regional and cross-network cost. Then the user-group would be divided further based on nodes’ interest,limited the search scope within an interest group,consequently reduced searching traffic and improved searching efficiency. Simulation demonstrates that the proposed algorithm can effectively divide the user-group,improving service efficiency.关键词
