New stream caching schemas for multimedia systems

In this paper a new multimedia caching strategy is proposed that includes several optimizations to the state of the art. This algorithm takes its roots from the interval caching algorithms but it evolves towards a more adaptive approaching that could obtain a better performance for variable bit-rate streams and serving media stored on multiple disks following different distributions. All of this without loosing competitiveness for constant bit-rate streams on a single disk. All this efforts are oriented towards the consecution of MUPIC (multi policy integrated cache), a cache architecture designed to fit the requirements of an integrated storage system that meet the requirements of deterministic applications, multimedia systems, and traditional best-effort applications altogether.
