Abstract: Disclosed are systems and methods for enabling an application developer to define CDN behavior (e.g., caching rules) alongside an application program code and embedded in the same source code. The systems and methods can be used to define CDN or edge caching behavior using custom cache keys that go beyond simply using a URL. The custom cache keys and source code CDN behavior definitions can be used to enable a graphical user interface to specify traffic rules in a codeless interface. The described embodiments can be used for defining general traffic routing, to test different versions of the application or to otherwise present different versions of the application to end users, while preserving cache keys and caching behavior at the edge and throughout the application distribution layers.

Abstract: The disclosure relates to a methods and apparatus to perform improved trickplay for higher speeds and high-latency networks. In one aspect, the method comprises receiving, in a processor, data comprising a video or audiovisual signal formatted in a sequence of chunks downloaded sequentially over a communications medium. When the processor receives a command to display the data at a trickplay speed that is higher than normal speed, the processor can begin to skip a number of chunks before downloading a next chunk in the sequence of chunks, decoding, and displaying the decoded chunk. The number of skipped chunks between each downloaded chunk may be a preset number and/or may be dynamically determined in the event that a downloaded chunk is skipped because it is not downloaded in time or if the expected download time of the next chunk is longer than the display time of the current chunk.

Abstract: One or more protocols between a control plane entity (e.g., a mobility management entity (MME)) and its peer nodes (e.g., mobile switching center (MSC) and/or short message service center (SMSC)) are enhanced to improve short messaging services for Internet of things (IoT) devices. Oftentimes, IoT devices enter an extended sleep mode during which they cannot be reached by the control plane entity.
