Abstract
A system for optimizing network bandwidth based on subscription rates from a plurality of requestors is disclosed as including a provider that provides provider data. The system also includes a first requestor that has requested the provider data at a first subscription rate and a second requestor that has requested the provider data at a second subscription rate. The second subscription rate is higher than the first subscription rate. The system further includes a plurality of intervening access nodes. Each intervening access node includes request information specifying any provider data being sent through the intervening access node and a corresponding subscription rate. The plurality of intervening access nodes are configured to decrease the rate to an adjacent node when a requestor decreases a requestor subscription rate such that all the rates along a common transmit path from the provider to an end requestor are optimized to maximize available bandwidth.
