Abstract
A computing device receives session description protocol (SDP) information including network parameters, from a plurality of client devices participating in an audio-video conference hosted by a primary conference host. The computing device selects a secondary conference host from the plurality of client devices. In response to receiving the SDP information from the plurality of client devices, the computing device sends a reply, including network parameter information identifying the secondary conference host, to the plurality of client devices of the audio-video conference. The computing device determines a failure of the primary conference host, wherein the failure is based, at least in part, on a violation of a threshold limit of a transmission rate of the primary conference host, and in response to determining the failure, the computing device sends information to activate the secondary conference host as the audio-video conference host, to the plurality of client devices.
