摘要
传统VPN系统存在不能根据状态自动调整运行,而且缺乏对运行状态的监控的问题,为此以OpenVPN为基础,提出一个VPN系统自动管理和实时监控解决方案,通过编写程序分析和理解服务运行状态,根据反馈触发执行相应管理程序,与管理端口进行通信调整服务行为,同时使用SNMP协议构造监控代理程序,对系统性能进行实时监控,使得管理员能够通过Cacti监控平台实时了解系统运行参数,达到保障VPN服务持续可靠和高效运行的目的。实验结果表明,该系统能够根据当前状态所设定的规则优化运行,并为管理员提供直观实时的性能视图。
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.
