Abstract

A system and computer-readable media are provided for transferring data over a network. In accordance with one aspect of the invention, the system includes a monitoring component, which monitors the level of actual network bandwidth utilization. The system also includes an identification component, which operates to identify a maximum monitored level of actual utilization. A calculating component then calculates a block size of data to transfer as a function of the maximum monitored level of utilization. The block size may be bounded between a maximum threshold value and a minimum threshold value. A receiving component then operates to receive the block size portion of the set of data over the network at one or more intervals. In another aspect of the invention, the block size is not bounded, and the system includes an interval adjustment component, which increases the size of the intervals when the block size is below a minimum threshold and decreases the size of the intervals when the block size exceeds a maximum threshold.
