Paper Abstract

In this paper, we propose a novel mechanism for providing deterministic service for Variable Bit Rate (VBR) streams at the disk. Previous approaches have relied on peak-rate of the stream for admission control for providing deterministic service. The proposed scheme allows statistical multiplexing of VBR streams at the storage system while providing deterministic service guarantees. We show that the proposed scheme can significantly improve stream throughput compared to peak-rate based schemes. We also evaluate the impact of other strategies such as data smoothing, statistical guarantees and higher stream startup latencies for improving the throughput of VBR streams. We show that stream startup latency can be effectively traded off for improving the stream throughput. We also show that smoothing and statistical guarantees do not provide significant additional improvements in stream throughput beyond the proposed approach.
