视频点播中基于用户行为的自适应资源搜索机制
User-behavior based self-adaptive indexing for VoD service
摘要
Abstract
This paper proposed a novel adaptive indexing structure which was based on user' s arbitrary behavior, called U-VoD. U-VoD group users according to user' s request pattern. It could reflect user' s request pattern and chunk popularity without any history statistics. It used the knowledge extracted from U-VoD to study an efficient popularity-aware prefetching mechanism. The simulation results demonstrate that it greatly reduces start-up delay with low server load under frequent seeking operations, especially for non-uniform access pattern.关键词
