METHOD AND SYSTEM FOR CLUSTER-WIDE PREDICTIVE AND SELECTIVE CACHING IN SCALABLE IPTV SYSTEMS |
摘要 |
A method for caching of stream data is accomplished by assigning for each video segment in the system a likelihood rating of future showing and then determining for each node that contains a copy of the segment a second likelihood value that reflecting a probability that the node will be used to serve streams for the segment. The future cost value of a segment copy is then predicted and preload orders are issued to nodes for segments with the per-copy likelihood above a predefined threshold.
