Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system obtains encoded video content, and transmits the encoded video content over a network for presentation at a communication device by a video player executing on the communication device. The encoded video content is decoded in a decoding process by a decoder of an operating system of the communication device to generate decoded video content; the decoded video content is analyzed by a complexity analyzer of the operating system to generate a video complexity report. The method also includes receiving the video complexity report over the network from the communication device, and adjusting a data rate for the encoded video content, based at least in part on the video complexity report, to generate adjusted video content for transmission to the communication device. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system directs video flows to a plurality of user devices located at network cells, and determines a first or second data usage priority for each user device. The system detects congestion at a cell of the network and/or in the video flows. The system also performs a first congestion-aware shaping procedure for video flows in the congested cell directed to user devices of a second priority located at the congested cell, and subsequently performs a second congestion-aware shaping procedure for video flows in the congested cell directed to user devices of the first priority located at the congested cell. Other embodiments are disclosed.

Abstract: Software downloads to Internet of things (IoT) devices are facilitated over a constrained network. In one embodiment a method comprises monitoring, by a network device comprising a processor, data determined to have been sent to a device for transmission to the device via a radio access network device of a wireless communication network, and determining, by the network device, a type of traffic associated with the data. The method further includes based on a determination that the data comprises firmware and that the type of traffic is of a traffic priority that is lower than a defined traffic priority, applying, by the network device, a low priority transport protocol to the data, wherein the applying comprises associating protocol information with the data representative of the low priority transport protocol.

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.
