Some embodiments provide an architecture for establishing a multi-participant conference. This architecture has one participant's computer in the conference act as a central content distributor for the conference. The central distributor receives data (e. g. , video and/or audio streams) from the computer of each other participant, and distributes the received data to the computers of all participants. In some embodiments, the central distributor receives A/V data from the computers of the other participants. From such received data, the central distributor of some embodiments generates composite data (e. g. , composite image data and/or composite audio data) that the central distributor distributes back to the participants.

Methods for establishing a direct peer-to-peer (“P2P”) connection between two computers are disclosed. In particular, the methods are designed to work in cases where one or both of the computers are connected to a private network, such private networks being interconnected via a public network, such as the Internet. The connections between the private network and the public network are facilitated by network address translation (NAT).

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.

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.
