OpenVPN server configuration file description (transfer), openvpn configuration file This article describes how to configure the configuration file on the OpenVPN server. In Windows, this configuration file is generally called server. ovpn. in Linux/BSD, this configuration file is generally called server. conf. Although the configuration file name is different, the configuration content is the same as the configuration method. This article is based on

As the application of the GMPLS/ASON technology in intelligent optical networks began to scale, we began to realize that the construction and development of transmission networks not only included the transmission hardware technology, the unified network management and control of the transmission network are also two difficulties for network construction and equipment technology development.

Therefore, the current IP network is extremely light, and the bandwidth utilization of the backbone network link is only 10% ~ 30%. Designing a new cost-optimized IP network transmission structure has become a hot topic in the industry.
