Research of Video Data Store Based on Cloud Storage

This paper put foreword a general architecture of cloud storage system, and discussed the model of video storage, and present a new method of video data store Algorithm based on weight. It uses discrete data algorithm which can not only locate video data object effectively, but also solves problems of objects copies mapping. Experiments indicate that the algorithm can accomplish data of data node efficient and balanced according to the load of storage devices, but also have a good performance for data recovery once there are invalid storage data nodes.
