Predictable File Access Latency for Multimedia
Dan Revel, Crispin Cowan, Dylan McNamee, Calton Pu, Jonathan Walpole · 1997
Multimedia applications are sensitive to I/O latency and jitter when accessing data in secondary storage. Transparent adaptive prefetching (TAP) uses software feedback to provide multimedia applications with file system quality of service (QoS) guarantees. We are investigating how QoS requirements can be communicated and how they can be met by adaptive resource management. A preliminary test of adaptive prefetching is presented.
