Provided are a data transmission method, device and system for a video conference. The method comprises: receiving, by a signaling processor, a call request for a video conference, the call request being a request initiated by a source terminal upon calling a target terminal; selecting, by the signaling processor, according to an acquired topology relationship among a plurality of media processors and state information of the plurality of media processors, one of the plurality of media processors; and notifying, by the signaling processor, the source terminal and the target terminal of the selected media processor, the selected media processor being used to forward a code stream of the video conference between the source terminal and the target terminal. The present invention addresses the problem in the related art of low operation efficiency and high cost of a video conference system caused by an NAT traversal of the video conference system realized by centrally deploying NAT traversal servers, thereby improving data transmission efficiency and disaster and fault tolerance ability of the video conference system. |
