摘要
近年来,视频业务逐渐成为互联网主流业务。及时把握热点视频,并以高效的方式传送给用户是运营商亟需解决的问题。为此,文中提出一种基于用户行为和时间衰减的视频热度计算方法,将视频按热度值进行排序,选取热门视频,以广播的形式传送给用户,帮助运营商优化缓存配置,提升服务质量。
Nowadays,video service has become the main service on the Internet. It is important for telecommunication operators to find out the most popular videos and then deliver the contents to customers in an efficient way. In this article,hot index is adopted to reflect the popularity of videos and a hot index computing method which is based on clients 'behaviors and time decay is proposed. Videos are then sorted by the hot index and those most-welcomed ones are delivered to customers via broadcast. In this way,telecommunication operators can better the configuration of caches so as to improve the quality of service.
