A new cache management algorithm for multimedia storage systems
Javier Fernández, Jesús Carretero, Félix O. García, J.M. Perez, Alejandro Calderón · 2003
Every storage platform intended to fit the requirements of the multimedia systems must incorporate a disk scheduling mechanism and a cache architecture that can handle their special needs. On the other hand, the general trend is to make integrated storage platforms that meet the requirements of deterministic applications, multimedia systems, and traditional best-effort applications altogether. In this paper we propose a new multimedia cache algorithm that imposes several optimizations to the state of the art. This algorithm has been designed to become part of an integrated storage system, including a proposal for an admission control algorithm that ensures the response time of the system for the accepted requests. This paper also presents an evaluation of the algorithm and compares it with other algorithms described in the bibliography.
