ABSTRACT:
System(s) and method(s) that, periodically or when triggered, adapt data rates in multiple tiers of a network are presented. A top tier feedback (FB) loop adapts on a longer time scale associated with its longer path transit time for FB communication messages from a wireless portion to a data source in the wire-line portion of the network. A bottom tier FB loop adapts very quickly, and on a shorter time scale that the top tier FB loop due to its shorter FB path transit time, at the wireless edge with sufficient speed to accurately adapt to fast-changing wireless conditions. The top tier provides efficient resource utilization down to the bottom tier, and the bottom tier provides efficient resource utilization within the wireless portion of the network. A middle tier(s) can be added as desired to provide a more gradual stepped adaptation from source to destination.
