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.

Abstract: Network function may be dissected and the common functions abstracted into inspection network function as the first hop, for example, of a service function chain. The inspection network function then inserts a value into the network service header (NSH) which may be used for the rest of the network functions of the service function chain.

Abstract: A system that incorporates teachings of the present disclosure may include, for example, initializing a boundary estimate for an optimization of a linear programming model describing a network of media servers for servicing requests for media content items from subscriber devices, where the boundary estimate is an estimate of an infeasible solution of the linear programming model, and calculating iteratively, using an exponential potential function, additional boundary estimates for the linear programming model, wherein the calculating resolves to an improved boundary estimate that corresponds to placement of copies of the media content items at the media servers subject to a set of constraints on storage capacity of media servers and on bandwidth for communication links in the network. Other embodiments are disclosed.

Abstract: An augmented reality device computationally processes an image frame against a first augmented reality profile stored in a local database. The first augmented reality profile includes first annotation content associated with a first object and is obtained from a second user device. In response to an object computationally processed from the first image frame satisfying a predetermined threshold of similarity with the first object in the first augmented reality profile, the first annotation content is rendered, on a display of the first user device, relative to the first object according to rendering instructions for the first annotation content.

Abstract: A processor performing functions of a video client may measure an occupancy of a video buffer, select a video chunk having a first video encoding bitrate based upon the occupancy, and provide a deadline for a delivery of the video chunk to a multipath transport layer module. The processor may further activate a deadline aware scheduler of the module when the occupancy exceeds a first threshold and when the deadline aware scheduler was previously disabled, and deactivate the deadline aware scheduler when the occupancy falls below a second threshold and when the deadline aware scheduler was previously enabled. The module may request packets of the video chunk from a video server and select at least one active interface for the video server to send each packet. The deadline aware scheduler may select whether a secondary network interface is to be an active interface or a non-active interface.

Abstract: Aspects of the subject disclosure may include, for example, a process that analyzes image content of an immersive video frame and identifies a first group of segments of the immersive video frame based on the analysis. The segments collectively span an entire space portrayed by the immersive video frame and the first group of segments spans less than the entire space. A size of a display region of an immersive video viewer is determined that spans less than the entire space and a second group of segments is determined based on the first group of segments and the size of the display region. Transport of the second group of segments, spanning less than the entire space, is facilitated via a communication network to the immersive video viewer for presentation, without requiring transmission of all of the segments. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, determining a deadline for completion of the transfer of the data content item to the mobile device. A set of locations of the mobile device is determined between the first time and the deadline, a candidate plurality of wireless base stations is identified, based on the forecasted plurality of locations, to wirelessly transfer a portion of the data content item to the mobile device during the time period. A utilization of a wireless base station of the candidate set of wireless base stations is forecasted during the time period, a transfer time is determined within the time period based on the forecasted utilization and the deadline, and the transfer time is provided to the mobile device. Other embodiments are disclosed.
