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.

摘要： A first computing device distributes audio streams to several computing devices of participants in a communication session. Some embodiments establishes a star network with the first computing device as a central network hub for receiving audio streams from other computing devices, compositing the audio streams and distributing the composited audio streams to the other computing devices. Through the star network, the first computing device receives audio streams from the other computing devices. The first computing device generates at least two different composite audio streams for at least two different computing devices by (i) identifying a set of silent participants in the communication session, and (ii) eliminating redundant audio processing operations that produce the same composite audio streams for different computing devices because of the identified set of silent participants. The first computing device sends each computing device the composited audio stream for the device.

摘要： Some embodiments dynamically designate one of several network nodes as a network hub of a star network, at the start of a network communication session among the several network nodes that is facilitated by a mesh network and the star network. Some embodiments dynamically designate a new network hub when the previously designated network hub leaves the communication session, which continues among the other network nodes. Different embodiments use different techniques to dynamically designate the network hub of the star network. For instance, some embodiments use communications transmitted along the mesh network to dynamically identify the network hub at the start of the network communication session or after the departure of a previously designated network hub.

摘要： A method and apparatus for adapting transmission to improve quality of service in a mobile wireless device that includes an application processor and a transceiver. An application service connection is established between the mobile wireless device and a remote device. The transceiver in the mobile wireless device monitors real time properties of a radio frequency access link that transports packets for the application service between the mobile wireless device and a wireless communication network. The transceiver provides local feedback to the application processor of updated values of the monitored real time properties. The application processor adjusts packet data generation and transmission in response to the updated values to manage quality of service for the application service connection. Packet data transmission adjustment includes active management of queues in the transceiver by the application processor, selectively dropping packets based on packet classifications and the local feedback information provided to the application processor.

摘要： For a first device participating in a video communications session with a second device, some embodiments provide a method that receives sets of encoding features supported by each of one or more decoders of the second device. The method selects an encoder for the video communication session from several encoders available to the first device. The method selects a set of encoding features of the selected encoder based on the sets of encoding features received from the second device. The method transmits an encoded video bitstream to the second device along with information identifying the selected features in order for the second device to select a decoder to decode the bitstream.

摘要： In one embodiment of the invention, service providers generate bloom filters with the user ID codes of registered users and exchange the bloom filters with one another. In response to a request to locate a first user, a first service provider will query its own registration database to determine if the first user is registered with the first service provider. If the first user is not registered with the first service provider, then the first service provider will query its bloom filters to identify other service providers with which the first user may be registered. A positive response from a bloom filter indicates that the first user may or may not be registered with the service provider associated with that bloom filter, and a negative response indicates with certainty that the first user is not registered with the service provider associated with that bloom filter.

摘要： A direct telephone dialing scheme for initiating internet telephone service from a web page is provided. The scheme allows a caller, using an internet telephone service, to place telephone call to a telephone number appearing on any web page directly from that web page. In one embodiment, a caller navigates to a desired web page on the internet and the caller dials a telephone number on that web page directly to initiate a two-way audio communication with the destination telephone number using an internet telephone service. The direct telephone dialing scheme of the present invention improves the accessibility and ease of use of internet telephone services. Furthermore, the direct telephone dialing scheme can be used with video, data, and fax a communications which are supported by the VoIP data communication standard.
