Abstract
One of the main challenges in disk system design for interactive VOD servers is how to achieve a good quality-of-service (QoS) guarantee. This paper proposes a queueing model for analyzing the I/O bandwidth required in order to achieve a certain level of QoS for a disk system design scheme that provides VCR emulation. The disk system design scheme employs a practice that requests no extra bandwidth to support interactive operations such as fast forward search and fast backward search. The proposed queueing model provides a complete analysis tool for pinning down the resource requirement issue and is verified through simulation for its validity.
