A scalable storage supporting multistream real-time data retrieval

摘要

This paper presents a new data placement scheme for continuous-media playback via a scalable storage system. Multimedia contents are segmented into data blocks for the Purpose of being stored, retrieved, and manipulated. If these Data blocks belong to some continuous media, then they Must be handled in a timely manner, for example, being re- Trieved before some deadline. One of the main challenges in Implementing the above system is the simultaneous retrieval Of a great number of different media streams from a very Large storage system.
