Abstract: 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.

Abstract: 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.

Abstract: A quick relay communication protocol is used by an initiating communication device (such as a wearable electronic device, e.g., a smart watch) and/or a recipient communication device (such as a companion electronic device to the wearable electronic device, e.g., a smart phone, a tablet computer or a laptop computer) to selectively communicate messages via different communication channels. Based on available connections and a communication constraint associated with a message, a processor executing a program module in an application layer in the initiating communication device provides transmission instructions to an interface circuit in the initiating communication device, which transmits a message to the recipient communication device based on the transmission instructions. When there are currently no available connections and the message is eligible to be communicated through a cloud-based relay server, the processor establishes a cloud-based connection with the recipient communication device via the relay server.

Abstract: A device implementing a system for multiway audio-video conferencing includes a processor configured to receive, from a first device, indication of a first channel and a second channel for communicating content for an audio-video conference session. The first channel and the second channel correspond to different types of communication interfaces. The processor is further configured to receive, from the first device, a first request to subscribe to a first content stream for the audio-video conference session via the first channel, and to subscribe to a second content stream for the audio-video conference session via the second channel, and in response to receiving the first request, forward, to the first device, the first content stream via the first channel.
