Data transmission method, device and equipment and readable storage medium

Abstract

The embodiment of the invention discloses a data transmission method, device and equipment and a readable storage medium. The method comprises the steps that a first terminal generates a data transmission request; the first terminal obtains the predicted socket number and a second penetrating extranet socket of the second terminal; the first terminal notifies the first network address translator to construct a first external network socket interval corresponding to the predicted socket number, and the first terminal sends a first penetration data packet to a second penetration external networksocket through each socket in the first external network socket interval; when the first penetrating external network socket exists in the first external network socket interval, the first terminal performs data transmission with the second terminal through the first penetrating external network socket and the second penetrating external network socket; wherein the first penetrating extranet socket is a socket which has sent the first penetrating data packet and has received a second penetrating data packet sent based on the second penetrating extranet socket. By adopting the method and the device, the success rate of point-to-point direct connection link establishment can be improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a data transmission method, device, equipment and readable storage medium. Background technique [0002] With the rapid development of Internet technology, the application of voice or video over Internet Protocol (Voice and Video over Internet Protocol, VVoIP) technology makes remote communication between people more and more simple, convenient and affordable. [0003] The direct transmission link refers to the network path through which the audio and video data packets generated by the VVoIP application are transmitted to the peer client. It is a point-to-point (peer-to-peer) direct link. The transmission link has the advantage of being simple and efficient, but since most terminals are located in the network address translation (Network Address Translation, NAT) intranet, the failure rate of establishing a direct transmission link is high, especially for symm...

[0003] The direct transmission link refers to the network path through which the audio and video data packets generated by the VVoIP application are transmitted to the peer client. It is a point-to-point (peer-to-peer) direct link. The transmission link has the advantage of being simple and efficient, but since most terminals are located in the network address translation (Network Address Translation, NAT) intranet, the failure rate of establishing a direct transmission link is high, especially for symmetric NAT- Symmetrical NAT intercommunication, the success rate of direct transmission link establishment is very low, which greatly reduces the versatility of direct transmission
