Research of Scheduling Algorithm Based on Priority in Data Nodes of Cloud Storage

Based on a school's teaching resources and video-on-demand services in schools, through building a cloud environment and studying the storage layer's video data storage of the cloud storage and the management manner, this paper proposes a sCheduLing algorithm based on Priority(SAP). According to the priority of data block, the algorithm sChedules on mastering the supply and demand of data block comprehensively and accurately, and solves the system's launch delay and the continuity of streaming media player.
