Method for providing high-availability transmission channel based on multiple network protocols

The method for providing the high-availability transmission channel based on the multiple network protocols comprises the following steps: determining a network protocol matched with a to-be-sent data packet from a preset network protocol set according to a data attribute of the to-be-sent data packet of an APP program of a first terminal; and after the second terminal responds to a data transmission request from the first terminal, selecting a matched gateway port according to the determined network protocol, constructing a one-to-one data transmission channel between the first terminal and the second terminal, and sending the encrypted data packet to be sent to the second terminal through the data transmission channel. According to the method, differentiated identification analysis is carried out on the data generated by each APP program of the first terminal, so that a proper network protocol can be selected in a targeted manner to realize data transmission according to the data attribute of the data packe
