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...
