Abstract: Aspects of the subject disclosure may include, for example, a method including identifying, by a processing system including a processor, performance indicators for a flow on a communication network. The system determines a size criterion for the flow, and a flow shaping criterion based on the data type and including a threshold value of a performance indicator. If the size criterion is met, the system monitors the performance indicators and initiates a flow shaping procedure responsive to the flow shaping criterion being met. The system also detects a change in the performance indicators due to the flow shaping procedure, and discontinues the procedure during the flow, responsive to the changed performance indicators not meeting the flow shaping criterion. The system may also resume the flow shaping procedure during the flow if the performance indicators subsequently meet the flow shaping criterion. Other embodiments are disclosed.

Abstract: A buffer classification system calculates first flow metrics for a first flow in response to receiving first packet level data. The system in response to receiving HTTP information, generates buffer emulation data and creates one or more data training sets using the first flow metrics and buffer emulation data, wherein training data used to create the one or more training data sets is further generated by computing an average throughput per second observed over different time windows during a video playback. The system in response to creating the one or more training data sets, generates one or more classifier rules used to determine a buffer condition of a flow. The system in response to receiving second packet level data, calculates second flow metrics for a second flow and predicts a buffer condition for the second flow based on the second flow metrics and the one or more classifier rules.

Abstract: Concepts and technologies are disclosed herein for adaptive bit rate mobile video objective testing. A system can receive a plurality of screen-capture frames, where each of the plurality of screen-capture frames corresponds to a respective frame of an adaptive bit rate video stream being displayed on a screen of a test device. The system can create a screen-capture video stream and determine that the screen-capture video stream corresponds to a reference video stream that is non-annotated. The system can obtain a reference video signature package, align the screen-capture video stream with the reference video stream using the reference video signature package, generate full reference video quality performance indicators, and determine delivery quality performance indicators for the screen-capture video stream. The system can join the full reference video quality performance indicators and the delivery quality performance indicators to form an objective quality of experience data structure.
