摘要： Some embodiments provide a method for managing a video conference between a first device and a second device. The method identifies a first ceiling bit rate for transmitting video conference data to the second device through the communication channel. The method identifies a current bit rate that is less than the first ceiling bit rate. The method receives networking data regarding the communication channel from the second device. The method determines, from the received network data, that the communication channel will sustain an increase in the current bit rate. The method increments the current bit rate. The method iteratively performs the receiving, determining, and incrementing operations until a determination is made that the communication channel will not sustain the increase in the current bit rate.

摘要： A first computing device distributes audio signals to several computing devices of participants in a communication session. In some embodiments, the first computing device serves as a central distributor for receiving audio signals from other computing devices, compositing the audio signals and distributing the composited audio signals to the other computing devices. The first computing device prioritizes the received audio signals based on a set of criteria and selects several highly prioritized audio signals. The first computing device generates composite audio signals using only the selected audio signals. The first computing device sends each computing device the composited audio signal for the device. In some cases, the first computing device sends a selected audio signal to another computing device without mixing the signal with any other audio signal.

摘要： Some embodiments provide a method of combining multiple streams of data packets into a single combined stream in a manner that facilitates accurate estimation of bandwidth of a connection over a network between two devices. When combining the streams into the combined stream, the method associates a set of packets from a first stream and a reference packet from a second stream to form a longer sequence of packets in the combined stream. The method sends the combined stream from a first device to a second device so that the second device can estimate the bandwidth of the connection between the first and second devices based on the inter-arrival times of the packets in the sequence of packets.

摘要： An apparatus, method, and machine-readable medium are described for establishing, maintaining and utilizing backup channels in a peer-to-peer (“P2P”) network. For example, in one embodiment, each mobile device can establish a primary P2P communication channel with one or more other mobile devices. Once the primary channel is established, each mobile device can use the primary channel to exchange secondary channel connection data and can subsequently open one or more secondary P2P communication channels with the other mobile devices. Upon detecting that the primary P2P communication channel has failed or has degraded below a specified threshold (e.g., a bandwidth or bitrate threshold), one of the secondary P2P communication channels can be automatically promoted to a primary P2P communication channel.
