Link-aware streaming adaptation
Technology to provide link aware streaming adaptation is disclosed. In an example, a mobile device can include one or more processors configured to: process a manifest file for an HTTP adaptive stream that is received at the mobile device from a node; determine a physical layer goodput of the mobile device with the node for the HAS; identify a segment throughput estimate for the HAS; and select a representation in the manifest file for a selected period based, on the physical layer goodput for the HAS and the segment throughput for the HAS.
