Abstract
Aspects of the subject disclosure may include, for example, a method including monitoring a video session to determine key performance indicators for cross-layer interactions between a network providing video session video data and user equipment receiving the video session video data, wherein the key performance indicators include a requested quality for a video chunk requested by the user equipment, a transmission control protocol congestion window size that corresponds to the video chunk requested by the user equipment, and an instantaneous radio access network throughput while downloading the video chunk requested by the user equipment, and determining a quality of service for the user equipment during the video session according to a residual length of content in a playback buffer for the user equipment based on the requested quality for the video chunk, the transmission control protocol congestion window size, and the instantaneous radio access network throughput. Other embodiments are disclosed.
