如何在湖北省地震网络系统中架构VPDN平台
|
摘要
湖北省地震系统约有100个站点需要利用无线网络系统进行信息传输,前期是利用自建的VPN网络,其传输速度受互联网的影响较大,传输速度较慢,甚至出现不能对仪器进行实时监控、数据不能按时收取、无法按时向国家台网中心报送数据的情况。而目前湖北省地震网络系统业务的拓展,需要进一步完善覆盖全省的数据传输网络,用于承载前兆无人职守系统、流动测震系统和移动办公系统。鉴于上述情况,湖北省地震信息网络部门通过分析各分支点所处的地理位置及数据传输的要求,最终使用中国电信的无线VPDN业务,组建湖北省地震数据监测VPDN网络系统。从而满足了数据传输的安全性、观测数据上报的安全性和地震分析预报的及时性要求。
There is a great need for about 100 stations of the earthquake administration of Hubei province to transmit information by use of the wireless network system.Early,the home-made VPN network was used,by which the transmission velocity is much affected by internet,so the velocity was very slow,even we could not moniter the instruments in real time,could not often receive the data on time,and thus could not report the data to state station network center on time.At present,the business of the seismic network system of Hubei province has extended and it needs improving the data transmission network to cover the whole Hubei and to support the anmared precursor system,mobile seismometry system and mobile office system.Seeing that,the department of earthquake information network of Hubei province,after analyzing the geographic location of each brouch point and their demands,decided to constract the VPDN network system for monitoring the seismic data of Hubei province by use of the wireless VPDN of China Telecom.Thereby,the sofety of data transmission,reporting the observations in real time and the analysis and prediction of earthquake on time can be guaranted.
