摘要： A transfer system (1) for transferring streaming data is disclosed. The transfer system comprises data sources (10a, 10b) configured to generate first streaming data (101), data input systems (20a, 20b, 20c) configured to generate second streaming data (102) based on the first streaming data (101), data reducing systems (30a, 30b, 30c) configured to generate reduced data (103) based on the second streaming data (102), and a data output system (40). The transfer system comprises also a service mesh (70)with data input proxies (21a, 21b, 21c), data reducing proxies (31a, 31b, 31c), and a data output proxy (41). Data transfer in the transfer system (1) is arranged through said proxies into and from the data input systems (20a, 20b, 20c), the data reducing systems (30a, 30b, 30c) and the data output system (40). A related method (300) is also disclosed.

摘要： Systems and methods are described implementing streaming analytics on a serverless compute system. A user can specify a data stream against which analytics should be conducted, serverless functions to be used to conduct the analysis, and criteria for the analytics, such as windowing criteria and aggregation criteria. The windowing criteria can specify windows of items within the stream that should be collectively analyzed. The aggregation criteria can specify how to group items within each window during analysis. A poller device can read data items from the stream, window and group the items according to the windowing and aggregation criteria, and invoke serverless functions to conduct streaming analytics on the data items. The poller device can further maintain state between invocations.

摘要： The subject technology provides for coordinating output of content during a multiuser communication session by initiating, by a server responsive to a request from a first participant device of a plurality of participant devices that are connected to a multiuser communication session, a media playback session for the multiuser communication session. A network identifier corresponding to the media playback session is generated at the server. The network identifier is transmitted by the server to remainder of participant devices connected to the multiuser communication session. Upon receiving an indication of a selection of the network identifier from at least a second participant device of the plurality of the participant devices at the server, the server causes media for the media playback session to be transmitted to the first participant device and the second participant device.

摘要： The present disclosure provides systems and methods for dynamically adjusting a bit-rate of encoded audio data. A buffer may receive audio data encoded at a first bit-rate. An audio data level corresponding to the amount of audio data stored within the buffer may be determined. The audio data level of the buffer may be determined to be within a buffer zone, and a bit-rate adjustment may be initiated after determining the audio data level is within a buffer zone.

摘要： Systems and methods for network bandwidth optimization, including transmitting sensor data from one or more sensors over a wireless network into a generated network slice, submitting a Quality-of-Service (QoS) request for one or more applications by specifying desired network slice characteristics, and predicting network bandwidth needed for granting the QoS request for the one or more applications using a cost function based on magnitude, direction, and frequency of error. Time-varying network bandwidth usage is continuously monitored, and new QoS requests for the one or more applications are periodically requested based on the monitoring. An updated prediction for updated bandwidth needed for the new QoS request is generated using the cost function, and network bandwidth reservations are iteratively adjusted based on the updated prediction for the new QoS request to provide an amount of network resources to the one or more applications to support the new QoS request.
