Abstract
In this paper, we investigate the buffer requirement to support a set of continuous media playbacks and develop an algorithm which dynamically changes the service mode of the playback to minimize the total buffer requirement. A certain amount of memory buffer is required in continuous media playback to synchronize the asynchronous disk I/O and synchronous playback operation. The most serious problem is the rate of increase in buffer requirement as disk utilization reaches 100%. We argue that in a large scale VOD server, where user access pattern is skewed, a certain playback can use the data blocks loaded by the preceding playback for the same file, and thus achieving less buffer requirement. We have developed an efficient algorithm to determine the service mode of each request.
