Abstract: With the development of the Internet, people’s demand for streaming media has been increasing, which puts forward higher requirements for the video server. The traditional cache replacement strategy in P2P video on demand system can not get a good user experience. In this paper, the traditional cache algorithm FIFO is improved, and a FIFO replacement algorithm based on Association Rules (FIFO-AR) is proposed. In order to further improve the performance of the cache replacement algorithm, a new Cache Replacement Algorithm based on Association Rules (CRA-AR) is proposed. According to the user’s play record and the popularity of the segment, and combined with association rule, the cache segment is obtained. The experimental results show that FIFO-AR and CRA-AR have higher hit rate and lower response time than the traditional cache replacement algorithms.

Key words: P2P, cache replacement, popularity, hit rate, association rule
