Abstract: A multimedia player downloads chunks (parts of the segment file) during the download of a segment of a stream of segments of a low-latency stream. The first chunks of a segment may be downloaded while the segment is still being written to the CDN server. A chunk-based prediction adaptation logic uses throughput measurements on a chunk instead of a segment and specifically looks at bursts in a sliding window. This data is used to build a prediction of future throughput by applying linear adaptive filter algorithms that may rely on recursive least squares. This adaptation logic leads to very accurate bandwidth predictions and as a consequence, better user experience, compared to existing adaptation algorithms.

The method includes obtaining descriptions of capabilities of a FLUS sink via a FLUS source; and sending, to an NBMP workflow manager of the FLUS system via a path that does not include the FLUS source and the FLUS sink, a request to create or modify a workflow of the FLUS system based on the descriptions of the capabilities obtained.

Abstract: Methods and systems for partially or fully distributed network verification are described. In partially distributed network verification, each network device generates a respective device-level binary decision diagram (BDD) representing the logical behavior of the respective network device for a network property of interest. The device-level BDDs from each network device are received by a verification service that performs verification by generating an input BDD representing an input header space, and applies each device-level BDD in a logical path from a source device to a destination device, and reports the output BDD. In fully distributed network verification, each network device is responsible for calculating a device-specific output BDD by applying a device-specific BDD, which represents the logical behavior of the network device, to a device-specific input BDD.

Abstract: In one embodiment, a device in communication with a service provider network obtains first information regarding a first call leg of a media session associated with a first endpoint. The device also obtains second information regarding a second call leg of the media session associated with a second endpoint. Both of the first and second endpoints are anchored in the service provider network. The device makes a determination that the media session is being hairpinned, based on the first and second information. The device sends, based on the determination, an indication message using Session Traversal Utilities for Network Address Translators (STUN) along the first call leg that causes the first endpoint to begin sending a flow of media packets.

Abstract: In an example, a system can include a web service interface (WSI) and a service directory for enabling communication between a web and non-web service. The WSI can be configured to communicate with the non-web service to receive reader data and/or writer data. The service directory can be configured to provide the WSI with non-web service subscriber data and/or non-web service publisher data for the non-web service in response to receiving the reader and/or writer data. The non-web service subscriber data identifies a web service as a subscriber of data provided by the non-web service and the non-web service publisher data identifies the web service as a publisher of data from which the non-web service is enabled to retrieve data. The WSI can be configured to provide the web service subscriber and/or publisher data to the non-web service to enable the non-web service to communicate with the web service.

Abstract: An approach for a software defined networking manager to perform a predictive analysis of proposed modifications to a software defined network (SDN) is presented. A method comprises receiving entity logical associations that are captured in a set of rules implemented in a SDN. Once a proposed modification to the entity logical associations is received, without implementing the proposed modification and without modifying the set of rules, impacted entity associations, from the entity logical associations, are identified. Upon receiving input indicating that the proposed modification is to be accepted, an updated set of rules for the SDN is generated by updating the set of rules based on the proposed modification, and the updated set of rules is implemented in the SDN.

Abstract: Many public events are recorded by members of the public, producing ‘user generated content’ or ‘user generated video’. Such content is often of unreliable and/or inconsistent quality. However, professional recordings of such events are often not possible and/or are inconvenient. In particular, multiple camera angles are often impossible to find using professional equipment and operators. The present invention provides a system and method in which user generated content may be collated, filtered and combined to produce a continuous professional quality audio-visual recording of an event.
