摘要
以搭建安全、稳定、便捷的地震系统远程数据传输网络为出发点,在陕西省地震系统现有广域网结构及业务需求基础上,分析以IPSEC+VPN或L2TP+VPN等方式进行远程数据传输存在的传输延迟、断记及维护困难等问题,结合虚拟专网技术的发展与VPDN技术的优势,研究将VPDN技术应用于陕西省地震网络的方法与可行性,设计与现有网络结构融合应用的方案,并对身份认证及差异组网两种管理控制方法对安全性的提升进行分析。
To build a safe, stable, convenient remote data transmission network in seismic system, the remote data transmission problems such as delayed or lost affected by internet in the existing VPN network structures are analyzed,which based on the structure and business needs of Earthquake Administration of Shaanxi Province existing WAN systems. And combining the advantages and development in recent years of VPDN virtual private network technology, the methods and feasibility of the application of VPDN technology in Shaanxi Province seismic network are studied. The approach of VPDN technology integrated in seismic network system is designed. Meanwhile, two management network control methods that enhance the network securities are analyzed. The new system meets the safety and timeliness requirements of remote data transmission and provides a guarantee of earthquake prediction.
