Active prefetching algorithm for streaming media based on natural number segmentation
Jianxin Liao · Journal of Communications · 2008
An active prefetching algorithm for streaming media based on natural number segmentation was proposed. The proxy prefetched actively the uncached data when the proxy delivered the cached data to the users. It improved the streaming media delivery quality and reduced playback jitter. Theoretical analysis determined the position that determined the prefetching starting time and the needed minimum cache size at proxy server. Simulation results show that natural number segmentation strategy can gain more byte hit ratio and less proxy jitter ratio than exponential segmentation strategy and near to those of uniform segmentation strategy under the circumstance of the same cache space.
