Abstract: An autonomous content delivery network (CDN) is partitioned into multiple virtual CDNs which are organized into a CDN hierarchy. Within the CDN hierarchy, a parent virtual CDN grants at least one privilege to at least one child virtual CDN. The parent virtual CDN has an instance of a CD service of a first type and the child virtual CDN has no instance of the CD service of the first type. The CD service of the first type is selected from: a rendezvous service; a streaming service, a configuration service, a control service, a collector service, and a cache service.

Abstract: During a Session Initiation Protocol dialog setup, a media gateway or container executes or initiates two or more applications that provide features during a conference call. The applications are applied to messages or data in the conference call based on a sequence order established during the setup of the conference call. The sequence order and the application identities are stored in a shared database. When a failure occurs during the conference call, the applications are reestablished in the reconstructed or reestablished conference call. The application reconstruction includes reinitiating the applications with the same sequence as previously established before the failure. As such, the user has the same features applied in the same way before and after the failure, which improves the systems performance and expected operation.

Abstract: Systems and methods for performing bit rate encoding are described. One of the methods includes receiving data indicating a change in a first connection speed that is associated with a first network. The change generates a second connection speed. The method further includes determining whether a media file is being downloaded. The method also includes determining that a current segment of the media file is being downloaded. The current segment is downloaded at a first bit rate and the first bit rate is associated with the first connection speed. The method includes determining whether the media file includes a remaining segment to be downloaded. The current segment precedes the remaining segment. The method includes identifying a second bit rate based on the second connection speed, receiving the remaining segment at the second bit rate, and stitching the remaining segment with the current segment.

Abstract: Embodiments of the invention provide for live encoding systems that can replicate a current encoded frame instead of re-encoding said current frame, and then adjust the replicated frame to different bitrates, resolutions, and/or contexts as necessary for the several different adaptive bitrate streams. In addition, various embodiments of the invention can extend a duration of a current frame being repackaged and/or re-encoded. Utilizing these and other techniques, live encoding systems in accordance with embodiments of the invention can more efficiently handle gaps in received data, slower feeding of data, and/or heavy loads on server hardware.

Abstract: A location query engine in a social networking system provides users with a subset of candidate locations based on location query received from a user. The social networking system identifies candidate locations from stored location data that has one or more attributes matching at least one attribute of the location query. The candidate locations are ranked based on social data determined from a user profile associated with the user, and the subset of candidate locations is selected from the ranking and provided to the user. Examples of social data used for ranking the candidate locations include locations associated with other users connected to the user, locations associated with objects connected to the user and locations previously associated with the user.

Abstract: The present describes low latency streaming using temporal frame transformation. An execution component in an edge server executes a first instance of an application. A server interface component receives, from a remote server, a resolution delta frame indicating differences between a high resolution first frame and a low resolution first frame of a second instance of the application or, alternatively, receives the high resolution first frame. A video manipulation component generates a motion delta frame by identifying differences between a low resolution first frame and a low resolution second frame of the first instance of the application. The video manipulation component generates a high resolution transformed frame by applying the resolution delta frame and the motion delta frame to the low resolution second frame.
