地震台站的数据共享和安全访问是基于IPv4的地震观测网络系统急需解决的关键技术问题，由于IPv4的地址局限，缺乏安全认证和数据加密措施，现有的地震观测网络系统建立在私有IP地址的行业局域网，只能实现基于台网级的数据共享访问。下一代互联网IPv6协议取代IPv4是必然趋势，本研究以实现台站级数据访问为目标，构建在IPv6网络环境下地震观测网络系统的安全组网模型，同时针对现有观测系统的特点，探讨IPv4地震观测系统过渡到IPv6的系统模型，为下一步IPv6技术在地震行业的推广应用打下基础。

The data sharing and safety access of seismic station are the two key technology problems that the seismological observation network system based on IPv4 needs to solve badly. Because of the address limitation and lacking safety certification and data encryption of IPv4, now seismological observation network system is set up in trade LAN of privately owned IP address, and can only accomplish the NetLevel data sharing. It is an inevitable tendency to replace the IPv4 with the Next Generation Internet Protocol IPv6. For the target of accomplishing StationLevel data sharing, we make up the safety network deployment model of seismological observation network system under the IPv6 environment, and inquire into the system model from IPv4 to IPv6 in accordance with the characteristics of now observation system. These research resources give a very good basis for more applications of IPv6 technology in the seismological observation technology industry in the future.
