Problems solved by technology
[0010] The purpose of the present invention is to solve the problem of increased server load and even unstable operation caused by the need for the server to forward the negotiation request message multiple times when the communication parties implement multiple communication strategies in the process of establishing a communication channel in the prior art, and the establishment of a communication channel. Issues with communication channels consuming a lot of time

Embodiment Construction
[0060] At present, when using a communication strategy to establish a communication channel in the existing technology, the calling party needs to forward the negotiation message to the called party through the server. If multiple communication strategies need to be tried during the process of establishing the communication channel, the server needs to Forwarding the negotiation request message will cause a sharp increase in the load of the server, resulting in unstable operation of the server. The present invention generates a communication strategy set generated by various communication strategies and sends it to the called party, and the communication parties establish a communication channel according to the communication strategy set, which avoids the server from forwarding the negotiation message multiple times, so it solves the problems existing in the prior art .
[0061] In order to make the above objects, features and advantages of the present invention more comprehe...

The invention discloses a method and device for establishing communication channel. The method comprises: a first terminal sends consultancy request message to a second terminal through server; the consultancy request message includes a first communication policy set which includes two or multiple communication policies; the second terminal obtains the first communication policy set from received consultancy request message, and generates the second communication policy set from the first communication policy set according to preset rule; the second terminal performs handshake according to the second communication policy set, if handshake successes, the first terminal and second terminal establishes communication channel. The invention solves problem of increased server load, and further performance degradation of server resulting from multiple forwarding for consultancy request message needed when multiple communication policies are performed and communication channel is established.
Description
technical field [0001] The invention relates to the field of computer communication, in particular to a method and device for establishing a communication channel. Background technique [0002] At present, P2P (Peer-to-Peer, point-to-point) network communication has been applied in many fields, such as instant messaging, point-to-point file transmission, point-to-point audio and video playback, and audio and video conferences. [0003] In order to realize P2P communication, the prior art provides multiple strategies for establishing P2P channels, such as P2P channels based on TCP (Transmission Control Protocol, Transmission Control Protocol), P2P channels based on UDP (User Data Protocol, User Datagram Protocol), and Based on UPNP (UniversalPlug and Play, Universal Plug and Play) communication channel, etc. However, since different communication strategies are adapted to different application programs and network environments, when two hosts in the network need to perform P...
