Abstract: In one example, a processing system including at least one processor obtains a transport control protocol flow associated with a video session that streams a video from a server to a client. The transport control protocol flow comprises a plurality encrypted packets exchanged between the server and the client. The processing system then reconstructs a hypertext transfer protocol transaction that is part of the streaming video session. The reconstructing is performed without decrypting the plurality of encrypted packets.

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.

Abstract: A more efficient over-the-air software push can be facilitated by leveraging a smart scheduling system for vehicles. The smart scheduling system can use location and network capacity data to prioritize over-the-air software pushes for vehicles. For instance, a vehicle, which is only operational during off-peak wireless network hours can receive a software push during the off-peak times because wireless network capacity is not an issue. However, vehicles, which are used primarily during heavy peak wireless network times can receive software in a prioritized manner based on location data, frequency of use, network capacity, etc.

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: Wireless video download rates are optimized by receiving, at a system with a computer that includes a processor and memory, a request to provide a piece of video content over a wireless network. The processor of the computer is used to determine whether to provide the video content at a first option that is as soon as possible or at a second option over a specified interval T. The interval T is calculated as a time for a destination device to download the video content at a rate level higher than encoding for the video content requires. Upon determining to provide the video content over the interval T, the video content is provided over the wireless network over the interval T to a client device that requested the piece of video content.
