Problems solved by technology

[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

Embodiment Construction

[0075] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0076] With the development of mobile terminal technology and the improvement of network bandwidth, more and more terminal users have the demand for large-volume data transmission, such as large file transmission or high-definition audio and video calls. According to the different ways of data stream transmission, data transmission links are divided into two types: direct transmission links and transit transmission links: the former is for direct P2P data transmission between users, and ther...

Abstract

The embodiment of the present application discloses a data transmission method, device, device, and readable storage medium. The method includes: the first terminal generates a data transmission request; the first terminal obtains the number of predicted sockets and the second penetration of the second terminal external network socket; the first terminal notifies the first network address translator to construct a first external network socket interval corresponding to the predicted socket quantity, and the first terminal passes each of the first external network socket intervals socket, sending the first penetration data packet to the second penetration external network socket; when the first penetration external network socket exists in the first external network socket interval, the first terminal passes the first The penetrating external network socket and the second penetrating external network socket carry out data transmission with the second terminal; the first penetrating external network socket has sent the first penetrating data packet, and has received the The socket of the second traversal data packet sent by the second traversal external socket. By adopting the application, the success rate of point-to-point direct 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...
