    Abstract: Network capacity planning based on application performance can include detecting a data session occurring on a network, identifying an application being used for the data session, where the application can include a video application, determining if a performance model for the video application exists, the performance model describing performance metrics and quality of service events associated with the video application, determining, based on the performance model, a capacity planning trigger for the video application, where the capacity planning trigger can include increasing network capacity based on the needs and a quality of service associated with the video application during the data session, and generating a command that, when executed by a network entity, causes the network entity to implement the capacity planning trigger on the network.

    Abstract: A processing system may determine, during a downloading of a first video chunk associated with a first time block of a video, a risk of stall condition, the first video chunk encoded at a first bitrate of a plurality of available bitrates, determine that a number of a received first plurality of frames of the first video chunk exceeds a threshold, transmit a request for a next video chunk associated with a next time block of the video and an indication to a source device to stop transmitting additional frames of the first video chunk, receive a second plurality of frames of the first video chunk from the source device that were transmitted prior to the source device receiving the indication, receive frames of the next video chunk, and play the first and second plurality of frames of the first video chunk, and the frames of the next video chunk.

    Abstract: Devices, computer-readable media, and methods for making a cache admission decision regarding a video chunk are described. For instance, a processing system including at least one processor may obtain a request for a first chunk of a first video, determine that the first chunk is not stored in a cache, and apply, in response to the determining that the first chunk is not stored in the cache, a classifier to predict whether the first chunk will be re-requested within a time horizon, where the classifier is trained in accordance with a set of features associated with a plurality of chunks of a plurality of videos. When it is predicted via the classifier that the first chunk will be re-requested within the time horizon, the processing system may store the first chunk in the cache.

    Abstract: Aspects of the subject disclosure may include, for example, obtaining, from a first source of information, a first bandwidth prediction, wherein the first bandwidth prediction is based upon historical bandwidth data that had been provided by a plurality of devices; obtaining, from a second source of information, a second bandwidth prediction, wherein the second bandwidth prediction is based upon network measurements, and wherein the network measurements are other than the historical bandwidth data that had been provided by the plurality of devices; selecting as a source of a future bandwidth prediction one of the first source of information and the second source of information, wherein the selecting is based upon a comparison of each of the first bandwidth prediction and the second bandwidth prediction to an actually obtained bandwidth of the device. Other embodiments are disclosed.

    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: Aspects of the subject disclosure may include, for example, setting a streaming rate cap for a client device; obtaining a bitrate ladder associated with the client device, wherein the bitrate ladder comprises a listing of a plurality of bitrates that the client device can request in connection with receiving streaming data; determining a boost rate for the client device, wherein the boost rate is greater than the streaming rate cap such that the boost rate enables the client device to receive the streaming data faster than the client device would otherwise receive the streaming data under the streaming rate cap, and wherein the boost rate is based upon the bitrate ladder; and enabling delivery to the client device of the streaming data up to the boost rate; wherein a network device is part of a network through which the streaming data is delivered to the client device. Other embodiments are disclosed.
