电力企业VPN管控系统体系结构设计

Architecture Design of Management and Control System for Enterprise Virtual Private Network

虚拟专用网络不仅具备低成本、良好的网络支持等特点,还具备租用专线的安全性优势,已广泛应用于拥有分支机构的大型企业。虚拟专用网络的管理已成为企业IT管理人员不得不认真面对的问题。文章在基于策略的网络管理、移动Agent等网络管理技术的基础上,提出了VPN管控系统架构。该架构能统一地管理包括VPN设备在内的网络设备,结合设备状态信息和预定义的管理策略,动态地实现全网管控,有效地帮助企业IT管理人员监控和管理企业VPN网络,优化网络资源的使用,减少维护工作的时间。

Virtual private network （VPN） not only possesses the low cost, inexpensive fees, and excellent support advantages of the Internet, it also has the benefit of the security as the leased line. How to properly manage the VPN is an issue which the enterprise IT engineers have to take seriously. This research is based on the new network management technologies such as policy-based network management, mobile Agent, etc., to design a VPN monitor and management system architecture. This system architecture integrates both VPN devices and general network devices, which can effectively assist the enterprise IT engineers to monitor and manage their enterprise VPNs in order to utilize the Internet resources, and to reduce the possible operation off time.
