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: In one example, a method and apparatus for web browsing on multihomed mobile devices having multiple communication interfaces are disclosed. In one example, the method establishes a primary multiple path transmission control protocol subflow for the transfer of a resource from a server to a user endpoint device. The method then determines a threshold of resource size. When the size of the resource is determined to exceed the threshold, the method establishes a secondary multipath transmission control protocol connection that cooperates with the primary multiple path transmission control protocol subflow for the transfer of the resource from the server to the user endpoint device.

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: Improved non-cellular (e.g., Wi-Fi) link integration with a cellular (e.g., LTE) network is described. The improved link integration can relate to utilizing an eNodeB device (e.g., residing in a radio access network portion of a cellular network) as an anchor point rather than a packet data network gateway device (e.g., residing in a core network portion of the cellular network) utilized by other approaches. The improved link integration can maintain full compliance with or support for other approaches, and can reduce signaling overhead, simplify quality-of-service management, and/or provide a more rapid reaction to changes of access, particularly in cases where the eNodeB device and a non-cellular access point device are co-located.

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.
