Problems solved by technology

This will undoubtedly increase the load on the OpenVPN server
[0004] In addition, in order to avoid data packet conflicts between different end users, multiple VPN instances created in the same OpenVPN server usually cannot be configured with the same external network IP, port and routing policy
This will undoubtedly occupy the limited resources of the OpenVPN server, which will further increase the load of the OpenVPN server

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] This application provides a data transmission method of an OpenVPN server in an SD-WAN system, which can be improved for the current OpenVPN server. Specifically, in the OpenVPN server, only one VPN instance can be enabled, and the VPN instance can uniformly receive external network data packets sent by clients of various end users through the external network interface of the OpenVPN server. Wherein, the external network interface may be jointly represented by the external network IP address of the OpenVPN server and the port for receiving external network data packets. The identification of the external network interface may include the external network IP address of the OpenVPN server and the identification of the port.

Abstract

The present invention discloses a data transmission method and server, wherein the method includes: based on the configuration file of the VPN instance, creating virtual network cards of at least two terminal users in the VPN instance; The connection information of the user, respectively establishes a VPN tunnel with each client of the at least two end users; the external network interface represented by the external network interface identifier receives the external network data message sent by the client of the end user, and Identify the target VPN tunnel to which the external network data message belongs; obtain the message processing policy of the target VPN tunnel, and after processing the external network data message according to the message processing policy, complete the processed external The network data packet is forwarded through the virtual network card bound to the target VPN tunnel. The technical solution provided by this application enables the OpenVPN server to reduce the overall load of the server when providing services to multiple end users.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a data transmission method and a server. Background technique [0002] OpenVPN (OpenSSL-based virtual private network) servers are being used by more and more enterprises due to their ease of use and high security. In order to improve the flexibility of the network connection, the OpenVPN server can be applied to the SD-WAN (Software-Defined Wide Area Network, software-defined wide area network) system at present. In an SD-WAN system, an OpenVPN server can provide services to multiple different end users. [0003] However, OpenVPN is usually a single-process application. If multiple end users are to connect to the same OpenVPN server, different VPN instances need to be run in the OpenVPN server, and each VPN instance can correspond to its own end user. This will undoubtedly increase the load on the OpenVPN server. [0004] In addition, in order to avoid data packet confli...
