By carefully studying the characteristics of IPTV (Inter- net Protocol TeleVision) live streaming service supporting timeshift functions, we find the default disk I/O strategies of universal OS can not provide satisfactory performance. Based on these observations, this paper proposes a set of dedicated disk I/O strategies in the design and implemen- tation of a live streaming server supporting timeshift func- tions. Our proposed strategies include asynchronous direct I/O, block-level data processing, media caching and me- dia prefetching, which are implemented in a live streaming server (ClearServer) developed by ourselves. ClearServer has been successfully deployed in the Shanghai Zhabei IPTV test-bed. Based on the deployment, detailed perfor- mance evaluation and test results demonstrate that the pro- posed strategies significantly improve several major perfor- mance metrics of the IPTV live streaming servers.
