基于3G无线网络的VPDN技术在海南气象业务中的应用
|
摘要
通过分析气象业务时效性强、7×24 h不间断运行的特点,结合海南气象网络结构的现状,充分挖掘无线网络的功能,深入研究基于3G的VPDN技术作为现有地面宽带的备份手段,规划设计了基于3G的VPDN线路备份方案,实现了具有高可用性的省-市县气象网络。详细阐述了组网方式和设备的功用,并给出了关键配置代码。该网络已经投入业务运行1年,无论是在日常业务中还是在重大气象保障中都取得了良好的效果。
By analyzing meteorological operation characteristic of strong timeliness and 7 ×24 h continuous running,combining with the situation of Hainan province meteorological network structure,the paper fully taps the function of wireless network,further studys the backup means of ground surface broadband based on 3G VPDN technology,plans and designs the VPDN line backup programs based on 3G,achieves high availability of provincecity and county meteorological network.The paper elaborates network way and equipment function,and gives key configuration code.The network has already putted into operation one year,no matter daily business or major meteorological security,the network achieves good results.
