ABSTRACT:
A method and apparatus is provided in which a data file acquisition program is operable to determine the data transfer speed of a plurality of devices containing a predetermined data file. The methodology calculates a priority ordering of the devices based upon the data transfer speed, and divides the data file request into portions for parallel access and delivery of the requested data file such that all of the portions are delivered to the user at approximately the same time whereby faster devices will be requested to access and deliver larger file portions and relatively slower devices will be assigned to access and deliver relatively smaller portions of the requested data file. Upon receipt of the portions, the requested data file is assembled for further processing by the user.
