Abstract:VPN system generally lacks the ability to adjust to the feedback from status and performance monitoring. To deal with this problem, an integration of feedback adjustment and real-time monitoring solution is introduced based on OpenVPN, which understands the status of VPN service, communicates with the management interface to adjust its behaviors, executes the administrative procedures according to the feedback automatically, and uses SNMP protocol to make an agent to provide real-time monitor, make the administrator understand system parameters through Cacti, ensures a continuous, reliable and high-efficiency vpn service. The experiments show that system can optimize the operation according to the status and rules, and provide a real-time performance view.
