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.application/pdf572682 bytesapplication/pdfen-USBandwidth; Computer simulation; Mathematical models; Queueing networks; Telecommunication services; Videocassette recorders; Quality of service (QoS); Video on demandjournal article10.1109/30.7934252-s2.0-0032632281http://ntur.lib.ntu.edu.tw/bitstream/246246/155142/1/08.pdf
