摘要： The embodiments described herein can dynamically adjust timing of network bandwidth estimations by adjusting a target frequency for sending probing sequences to one or more receivers of content. The receivers receive these probing sequences from a transmitter and respond to the transmitter with network bandwidth estimations. In one embodiment, the probing sequences can use the content itself to create the probing sequences. The embodiments can be used in video conferencing applications to control how a transmitter of content can adjust transmissions based upon the network bandwidth estimations. In one embodiment, a policy can be used at a transmitter to begin a video transmission with a high frequency target for sending probing sequences (with, e.g., smaller length probing sequences) and transition to a lower frequency target (with, e.g., longer length probing sequences) when network bandwidth deteriorates and then return to the higher frequency target when the network bandwidth improves.

摘要： A device implementing dynamic redundancy may include at least one processor configured to receive, from another device, packet reception data corresponding to video data previously provided for transmission from the device to the other device and determine, based at least in part on the packet reception data, an amount of redundancy to apply to video data provided for transmission to the other device. The at least one processor may be further configured to determine, based at least in part on the amount of redundancy, an encoding scheme for applying the redundancy to the video data. The at least one processor may be further configured to apply the amount of redundancy to the video data based at least in part on the encoding scheme to generate redundant data items and provide the video data and the redundant data items for transmission to the other device.

摘要： A device implementing a system for packet loss management may include a memory and at least one processor configured to identify a plurality of categories of packets provided for transmission to an electronic device. The at least one processor may be further configured to determine a respective packet loss value for a respective category of the plurality of categories of packets. The at least one processor may be further configured to identify a particular category of the plurality of categories of packets for which the determined respective packet loss value satisfies a packet loss condition. The at least one processor may be further configured to adjust subsequent transmission of packets in the particular category of packets based at least in part on the packet loss condition being satisfied by the determined respective packet loss value for the particular category of packets.

摘要： A device implementing a system for multipath connection management may include first and second local communication interfaces, and a processor configured to establish a primary connection for communicating between the first local communication interface and a first remote communication interface of an other device, and a secondary connection for communicating between the second local communication interface and a second remote communication interface. The processor may be configured to transmit application and control data over the primary connection and concurrently transmit a copy of control data over the secondary connection. The processor may be configured to determine that a degradation of the quality of the primary connection is attributable to the other device. The processor may be configured to switch the secondary connection to the first local communication interface and the second remote communication interface. The processor may be configured to transmit a copy of the application and control data over the secondary connection.
