클러스터드 VOD 서버에서 가변 비트율을 고려한 스트라이핑 정책

Abstract

In a VOD server, media data are usually encoded by VBR compression technique such as MPEG, therefore, media stream rates vary. We propose a striping strategy called VCS considering VBR compression in Clustered VOD servers. Simulation are conducted to evaluate and compare the new strategy with a known striping strategy. The results show that the VCS strategy improves the performance.
