Abstract: Aspects of the subject disclosure may include, for example, a method including providing a video presentation to user devices. A latency related to the video presentation is determined for each device; a high-latency user device is identified having greater latency than other, low-latency devices. Field of view information is analyzed for each of the low-latency devices; based on the analyzing, a field of view of the high-latency user device is predicted. In accordance with the predicting, a predicted viewing map for the high-latency user device is generated. The video presentation for the high-latency user device is adjusted based on the predicted viewing map. Other embodiments are disclosed.

Abstract: In one example, a processing system including at least one processor may obtain at least one frame of a volumetric video, obtain a first viewport of a client device, render a plurality of two-dimensional subframes comprising two-dimensional projections of the at least one frame of the volumetric video, based upon the first viewport of the client device, and transmit the plurality of two-dimensional subframes to the client device. In another example, a processing system including at least one processor may request a volumetric video from a network-based proxy, provide a viewport to the network-based proxy, obtain a plurality of two-dimensional subframes from the network-based proxy in accordance with the viewport, select at least one of the plurality of two-dimensional subframes to present, and display the at least one two-dimensional subframe that is selected.

Abstract: The concepts and technologies disclosed herein are directed to parallelism for virtual network functions (“VNFs”) in service function chains (“SFCs”). According to one aspect, a packet processing system can receive instructions to process, in parallel, at least a portion of a plurality of data packets associated with an SFC including a plurality of VNFs. The system can create a copy of at least the portion of the data packets. The system can send the copy of at least the portion of the data packets to at least two VNFs. The at least two VNFs can process, in parallel, the copy of at least the portion of the data packets. The system can receive, from the at least two VNFs, processed packets including the copy of at least the portion of the data packets and processed, in parallel, by the at least two VNFs. The system can combine the processed packets.
