| Abstract: | With the rapid development of computer and network technology and multimedia technology, the parallel VOD system is gradually spreading in use. The improvement of the service quality requires video server is more reliable. This paper introduces the present construction of research for VOD. Then we put forward a pre-store replication technology thought comparison of current popular video replication plans. This method considers the inefficiency of disks, which does not need extra read time and make timely action on users request and makes the system more reliable. |
