本文简要介绍了国家重大基础设施项目-中国大陆构造环境监测网络系统建设项目中网络通信部分的技术思路与技术实现。该系统摆脱了传统设计思路,充分利用现有网络通信资源,在已有的中国地震行业网络基础上,通过多种广域网通信技术、虚拟组网技术、加密技术的灵活运用,实现了天地融合、安全可靠,横跨6家部委单位,覆盖全国31个省市地区、境外2个国家的大型专用广域网通信系统,同时大幅节省了网络通信系统建设经费的投入以及后续运行中的信道租用费与系统维护费。后续国家十二五重点项目地震烈度速报与预警工程的网络通信系统的设计思路与组网模式参考了该系统。
This article briefly introduces the technical ideas and technical realization of the network communication part of the national major infrastructure project - the construction environment monitoring network system construction in mainland China. The system gets rid of the traditional design ideas and makes full use of the existing network communication resources. Based on the existing earthquake industry network in China, through flexible application of various WAN communication technologies, virtual networking technologies and encryption technologies, the system has realized the integration of the world, Safe and reliable, across six ministries and units, covering 31 provinces and cities nationwide, two countries outside the large private wide area network communication system, while substantial savings in network communication system construction investment and follow-up operation of the channel lease fees and systems Maintenance fee. Follow-up National Twelfth Five-Year Key Project earthquake intensity quick warning and early warning project network communication system design ideas and networking models refer to the system.
