ABSTRACT:
A data organization scheme for movies stored on a video server. The method utilizes the available bandwidth and space in the I/O system to avoid the data contention in the ATM. Basically, parts of the hot movies are replicated on the server unit. Most of the requests to the hot movie are directed to this unit. But if the server unit can not deliver the required video object within the required time limit (because of the large queue length) the video object is transported from the other server units through the ATM network. All the requests that are fulfilled locally by the server unit will not go through the network. Thus, the traffic through the ATM decreases on the expense of increasing the disk utilization.
