摘要
IPv6网络是互联网发展的必然趋势。而从IPv4网络过渡到IPv6网络将是一个漫长的过程,在这个过渡时期两者将并存。本文介绍了IPv6的基本概念和目前常用的IPv6组网技术,以及在四川省地震局的应用。由于地震信息网络是"国家—省—台站、市县"三层结构,在IPv6示范台站建设时仍遵循该结构,在四川省地震局和成都地震台增加了IPv4/v6双协议路由器,分别接入本地IPv4网络,通过隧道封装技术,由四川省地震局汇接成都地震台,再上联到中国地震台网中心,从而实现地震信息IPv6网络的互联互通。
The use of IPv6 network protocol is an inevitable development trend of Internet. The transition process from IPv4 to IPv6 networks will take a long period. In this transition period two protocols will co-exist. This paper introduces the basic concepts of IPv6,IPv6 networking technology currently used and applications of IPv6 in the seismic data transmission in Earthquake Administration of Sichuan Province. The seismic information network is divided into three level structures,which means state,province and seismic station. The new IPv6 used in demonstrative seismic station will satisfy the structure of three levels and the Tunnel Encapsulation Technology is also used. Routers with both IPv4 and IPv6 are installed in the Seismic Standard Station of Chengdu to transit successfully the seismic data to China Earthquake Network Center.
