| Abstract: | Current popular video storage plans for parallel VOD system are analyzed and compared. A replication algorithm with forward recovery is put forward. This algorithm considers the inefficiency of hardware and guarantee the system to approximate the break times of the video and take over data transmission, which makes the system more reliable. Based on date node of parallel VOD system, accomplishing process of this plan is expounded in detail. |
