Problems solved by technology

However, TCP point-to-point communication cannot be directly performed between traditional network devices located in different regional networks. Although network address translation (NAT) hole punching technology can be used to penetrate, the existing TCP-based NAT hole punching technology can penetrate The success rate of penetration is low, and these complicated situations limit the application and development of network equipment to a certain extent

Abstract

A data transmission method is provided. The method includes: establishing, by a first NAT-T sub-module of a TCP server proxy module, a transmission channel with a second NAT-T sub-module of a TCP client proxy module via a NAT-T signal server; and transmitting, by a client, a data packet to a server module in the transmission channel via the TCP server proxy module and the TCP client proxy module; wherein when a first reliable transmission sub-module of the TCP server proxy module and a second reliable transmission sub-module of the TCP client proxy module receive the data packet, the first reliable transmission sub-module and the second reliable transmission sub-module detect the transmission channel and the data packet, and suitably control the transmission channel and the data packet according to a detection result so that the data packet is reliably forwarded between the client module and the server module.

Description

technical field [0001] The present invention relates to a data transmission system, method and recording medium thereof, and in particular to a data transmission method, system and recording medium for transmitting TCP (Transmission Control Protocol, Transmission Control Protocol) data packets. Background technique [0002] In recent years, with the development of Internet (Internet) bandwidth access technology, more and more devices can access the Internet, such as Internet TV, electric lights, air conditioners, refrigerators, network cameras and other devices. The many conveniences and practicability that network equipment brings to users make it widely used in places such as homes, communities, businesses, and office buildings. [0003] When performing TCP point-to-point communication, traditional network equipment requires the user to assign a unique public network IP address and perform corresponding network configuration on the network equipment. At the same time, due...
