基于GAP技术的地震信息网络系统改造方案

摘要

Earthquake information network system of Jiangsu province is a unified platform of regional seismic data transmission, data exchange, and data storage and information service. Aiming at the existing problems of the network system, an updating scheme is put forward. There are mainly: to physically separate the transmission system and Internet by GAP, to upgrade the key equipment and links bandwidth of the network, to increase network security equipment. Through those technical means, the network system achieves a safe, stable operation target, both to satisfy the needs of the information and data transmission, exchange, storage and diversified applications of seismic, and to meet the requirements of three level safety management of information system. The scheme can provide a useful reference for optimizing the seismic information network system.%江苏省地震信息网络系统是全省区域地震数据传输、数据交换、数据存储及信息服务的统一平台。针对网络系统目前存在的问题，提出了改造方案，即通过使用隔离网闸将业务传输系统和互连网进行物理隔离，升级网络关键设备和链路带宽，增加网络安全设备等技术手段，使网络系统达到了安全、稳定运行的目标，既满足了地震信息数据传输、交换、存储及多元化应用等的需求，又符合信息系统三级安全管理要求，可以为地震行业信息网络系统优化建设提供有益参考。
