Abstract
A bandwidth estimation algorithm on shared links detects peaks and/or average per-user bandwidth. Estimating is performed at the transport or IP layer with no assistance from lower layer (PHY, MAC, etc.) and the techniques can be used for any of adjusting the level of video optimization to the available bandwidth; driving QoS decisions at the transmitter based on available bandwidth; improving QoS enforcement during transitions among hybrid technologies on a wireless links; and correcting estimates on devices delivering bursty payload.
