ABSTRACT:
A method and apparatus is provided in which a site selection program is operable to selectively initiate sample testing of data transfer speed of a plurality of sites containing a predetermined data file. The methodology calculates a priority ordering of the plurality sites based upon the sample testing of data transfer speed, and divides the data file 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 channels will be requested to access and deliver larger file portions and relatively slower channels 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.
