Virtual private network connection method, server, client and storage medium

Abstract

The embodiment of the invention relates to the field of transmission of digital information, and discloses a connection method of a virtual private network, a server, a client and a storage medium. The connection method of the virtual private network is applied to a registration server. A connection request sent by a virtual private network to a VPN client is received, and the connection request is used for requesting connection with a VPN server. The connection information of the available VPN server and a network quality detection strategy returns to the VPN client, wherein the network quality detection strategy is a strategy for detecting the network quality of the available VPN server; wherein the VPN client selects the VPN server to be connected for connection according to the networkquality detection strategy. According to the embodiment, the number of VPN servers can be increased conveniently, the success rate of accessing the VPN servers is increased, and the network quality of connecting the VPN servers is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of digital information transmission, and in particular to a virtual private network connection method, server, client and storage medium. Background technique [0002] A virtual private network (Virtual Private Network, referred to as "VPN") is a tunnel that provides secure data transmission between enterprises or between individuals and companies. OpenVPN software has been widely used in network applications, not only can realize secure point-to-point communication, but also point-to-multiple distributed services. During the existing OpenVPN usage, the availability of network services is improved by configuring multiple OpenVPN servers in the OpenVPN client configuration file. The following describes the process of OpenVPN connecting to the OpenVPN server: If multiple openvpnservers are configured in the OpenVPN client configuration file, the VPN client software will try to connect to the o...

Problems solved by technology

[0003] The inventors have found that there are at least the following problems in the related technologies: when the IP information of the VPN server changes, the configuration file of the VPN customer service end needs to be changed, or the domain name resolution of the VPN server needs to be changed, which leads to the need to modify the VPN client if the number of VPN servers is increased. Updating the configuration file of the client or updating the domain name resolution of the VPN server increases the workload and increases the cost. In addition, before the connection is successfully established in openVPN, there are reasons for connection failure, which reduces the success rate of connecting to the VPN.
