Paper Abstract

This paper discusses disk system design that supports VCR-like interactive video-on-demand (VOD) with a good quality-of- service (QoS) guarantee. The guarantee of QoS is based on a practice that requires no higher data bandwidth to support a stream switching from the normal playback mode to a fast search mode while providing VCR-like visual feeling. The main issue studied in this paper is how to figure out the I/O bandwidth required in order to achieve a certain level of QoS. This paper presents a queueing model to tackle this problem and uses simulation to verify the validity of the queueing model. This paper also addresses the related implementation issues.
