Abstract: Continuous media, such as video and audio, and text, have different need for file system because of different characteristics. This paper proposes a layered file system model that can integrate some media data types, optimize the resource allocation and improve the utilization and quality of service on different layers according to the media characteristics of real-time, periodicity and so on. The model is validated by building a prototype system.
