基于虚拟专网(VPN)的交通观测系统研究

Traffic Observation System Based on VPN

随着交通观测系统建设的快速发展,系统内的各个观测站点与数据中心之间的通信需求、系统与外界共享数据信息的部门之间的通信需求将会大幅度增强,随之而来的问题是相互间的信息传输模式和网络互连架构也越来越复杂。现行的数据通信的方法将会遇到更多新的挑战。在这样的背景下,基于公用网络的动态、安全的连接解决方案——虚拟专网络(VPN)就成为交通观测系统网络建设的新选择。VPN技术的成功引入可以从根本上满足低通信费用和高灵活性的双重需求,更重要的是它可以提供与专用网络相媲美的通信安全保障。

With the rapid development of traffic observation system,the needs of communications between sites and data center and between system and the outside world to share data will be significantly enhanced.The resulting problem is that the mutual information transfer mode network and interconnection framework have become increasingly complex.The current method of data communication will be confronted with new challenges.Against such a background and based on the public network of dynamic,VPN traffic observation system,which is a secure connectivity solution,has become a new choice of network construction.The VPN technology can meet the needs of low-cost and high flexibility of the double demand successfully.More importantly,it can provide the communication security which matches the quality of private network.
