There has been a large amount of media in recently years. Combined with growing users, how to quickly address the video requests from users with low delay is important for industry. In other words, to allocate resource (i.e. media) appropriately according to different situations is critical. This paper proposes strategies which make video replica and put it nearby users (set-up boxes) previously. The proposed strategies not only consider the popularity of the media but also consider its hot time, i.e. the time slots which most of the users access it. The experiment result shows that with the proposed strategies, user requests can be quickly addressed and the overall network traffic load can be reduced.
