Abstract: A method, an apparatus, and a system for implementing private network traversal are disclosed, where a message exchanged between a TURN server in a public network and a communications terminal in a local area network is transmitted through a pre-established websocket connection. The method includes: receiving, by the TURN server, a resource allocate request sent by the communications terminal, allocating a relay address and a resource port for the communications terminal; receiving a TURN data packet sent by the communications terminal, where the TURN data packet includes communication data and a multiplexing identifier, and sending the communication data to the remote node through the communications channel identified by the multiplexing identifier, thereby solving a problem in an existing TURN technology that in case that a firewall only opening an HTTP port is deployed, communication between a communications terminal in a local area network and a remote node cannot be implemented.

Abstract: Embodiments of the present invention relate to a method, an apparatus and a system for transmitting a media stream. The method is executed by an access terminal, includes: establishing a real-time collaboration channel between the access terminal and a network computer; sending through a first VDI channel to the network computer an operation instruction input by a user; receiving a real-time collaboration message that is sent through the real-time collaboration channel by the network computer; performing, through the network computer, media negotiation with a communication device, so as to determine a media attribute parameter that is used to transmit a media stream between the access terminal and the communication device; and transmitting, by the access terminal, a media stream mutually with the communication device according to the media attribute parameter determined through the media negotiation.
