Abstract: Techniques are disclosed for the identification of applications from communication sessions of network traffic between client devices and the generation of application-specific metrics for network traffic associated with the applications. In one example, a router obtains metrics for a plurality of packets. The router determines a session of a plurality of sessions associated with each packet. For each determined session, the router generates metrics for the session from the metrics of the packets associated with the session and determines an application of a plurality of applications associated with the session. For each determined application, the router generates metrics for the application from the metrics of the sessions associated with the application and transmits, to a device, the metrics for the application. In some examples, the router generates the metrics for each application on a per-client, per-next-hop, or per-traffic class basis.

Abstract: A Byzantine fault-tolerant distributed computing system of nodes configured to process client requests, executes a leader-based total order broadcast (LBTOB) protocol. The computing system concurrently executes multiple instances of the LBTOB protocol at the nodes, on respective disjoint partitions of the client requests, and the disjoint partitions are assigned to the instances using a deterministic function of a state of the system. The computing system multiplexes outputs of the executing instances in an ordered log of the client requests, and the ordered log is maintained at each of the nodes.

Abstract: A streaming device may request and download multi-layer video segments based on a number of factors including the artistic interest associated with the video segments and/or the status of a buffer area managed by the streaming device. The multi-layer segments may be coded using scalable coding techniques or a combination of scalable coding and simulcast coding techniques by which each of the video segments may be coded into one or more representations of different qualities and/or bitrates. When requesting the multi-layer segments, the streaming device may ensure that the fullness of the buffer area falls between a buffer underflow threshold and a backfilling threshold under various network conditions. The streaming device may estimate the available network bandwidth in order to facilitate the scheduling decisions. The streaming device may consider the artistic interest associated with the video segments during scheduling and may give priority to those segments with higher artistic interest.

Abstract: A control device receives information, e.g., network status information and network loading information, from a plurality of service provider networks and device capability information and status information, from a plurality of user equipment (UE) devices. UEs subscribe to multiple service provider networks. In some geographical regions, coverage is provided by more than one network. The control device generates and sends device profile to network mapping information to UEs on an individual UE basis, e.g., for geographic regions, e.g., 3D regions, where multiple networks are available. Device profile to network mapping information sometimes includes criteria, e.g. rules, parameter, limits, etc. An application on the UE uses the received device profile to network mapping information, along with position information, to select a network/profile to use at a given time. Altering the information provided to one or more UEs allows the control device to perform load balancing between networks.

A specific solution is as follows: After detecting that screen-off duration of the terminal device is greater than first duration, the terminal device sends a transmission control protocol reset packet to an application server of a to-be-controlled application, so that the application server disconnects a TCP connection to the terminal device. Therefore, after the terminal device enters the doze mode, the power consumption of the terminal device is further reduced. The embodiments of this application are used to reduce power consumption of the terminal device.

Abstract: The disclosed techniques improve the efficiency and functionality of virtual event platforms by segmenting users that attend a virtual event. An event segmenter retrieves user data for each attending user. The user data can include interaction data from past virtual events, topic data derived from user activity, social data defining the user's social relationships, etc. The event segmenter uses the user data to identify topics of interest for each user and generate an interaction graph for each user based on the topics of interest. The event segmenter uses the interaction graphs to generate user segments for the virtual event and assign each user to a user segment based on matching topics of interest. A model optimizer collects and analyzes user activity within each user segment to train the event segmenter to modify interaction graphs. In this way, the event segmenter can improve the virtual event segmentation process over time.
