Problems solved by technology

When this data transmission method is abnormal in the network (unpredictable abnormalities, such as network fluctuations / line failures, etc.) and the data connection is interrupted abnormally, the VPN data transmission will also be interrupted.
If you encounter an abnormality that cannot be restored to normal for a long time, the communication between the two parties will be unable to communicate for a long time

Embodiment 1

[0025] An embodiment of the present invention provides a VPN data transmission method, comprising the following steps: establishing a VPN tunnel between a first communication terminal and a second communication terminal; establishing a session connection through the VPN tunnel; establishing multiple data connections, and transmit data through the plurality of data connections. By establishing multiple data connections between communication terminals, if any data connection is abnormal, it will not affect the data transmission on other data connections, which enhances the anti-interference ability of data transmission between communication terminals and effectively guarantees The success rate of data transmission.

[0026] In the case that at least one communication terminal has multiple IP interfaces, IP interfaces of two communication terminals can be respectively selected to establish multiple data connections. see figure 1 As shown in the schematic diagram of establishing...

Embodiment 2

[0042] Such as Figure 5 The shown embodiment of the present invention provides a VPN data transmission device, the VPN data transmission device includes: a VPN tunnel module for establishing a VPN tunnel between the first communication end and the second communication end; a session connection module for Establish multiple session connections between the first communication terminal and the second communication terminal through the VPN control channel; the data connection module is used to establish multiple session connections between the first communication terminal and the second communication terminal through the session connection Data connection; a data transmission module, used for transmitting data between the first communication terminal and the second communication terminal through multiple data connections.

[0043] Optionally, the first communication end includes at least one first IP interface, the second communication end includes at least one second IP interfac...

Abstract

The invention discloses a VPN data transmission method and a VPN data transmission device. The VPN data transmission method comprises the following steps of establishing a VPN tunnel between a first communication terminal and a second communication terminal; establishing a session connection through the VPN tunnel; and establishing a plurality of data connections through the session connection, and transmitting data through the plurality of data connections. According to the method and the device, the VPN control channel is established between the communication terminals, the data connectionsare established on the VPN control channel, the data connections can be used for transmitting data, and the data transmission on other data connections cannot be influenced when any one line is abnormal, as long as one data connection is normal, the data can be transmitted normally, so that the anti-interference capability of data transmission between the communication terminals is enhanced, and the success rate of data transmission is effectively guaranteed. The method and the device can be widely applied to the field of VPNs.

Description

technical field [0001] The present invention relates to the VPN field, in particular to a VPN data transmission method and a VPN data transmission device. Background technique [0002] In the prior art, the VPN (Virtual Private Network, virtual private network) transmission mechanism is that both communication parties first establish a VPN tunnel. Then the two sides of the communication establish a session connection in this tunnel, and then establish a data connection to transmit data on this session connection. When this data transmission method is abnormal (unpredictable abnormalities, such as network fluctuations / line failures, etc.) and the data connection is interrupted abnormally, the VPN data transmission will also be interrupted. If there is an abnormality that cannot be restored to normal for a long time, the communication between the two parties will not be able to communicate for a long time. Contents of the invention [0003] The present invention provides a...
