摘　　要：随着网络的普及和3G等无线网络等技术的不断发展,通过3G或GSM构建专用网的技术也日渐成熟。利用专用虚拟网进行网络通讯的需求越来越迫切。在相对偏远且分散的水文站点间,构建专用广域网,不仅耗资大,而且实施困难。借助于互联网,通过L2TP VPN加密技术构建水文虚拟网,既解决了水文站点的实时网络报汛问题,还实现了内部资源的共享,实现了分散站点在没有专用内部网络情况下对内部办公自动化系统的访问。经过近一年的生产运行,山东各水文、水位站点的报汛时效性得以大幅提高,差错率几近零的水平,取得了明显的效益。With the development and popularization of the network and 3G wireless network technologies,special network technology constituted by 3G or GSM has become more mature using the 3G or GSM.The use of VPN network communication becomes more and more urgent.To constitute wide area network in a relatively remote and distributed hydrological station building,not only cost largely but also is a difficult work.By means of internet,via L2TP VPN encryption technology in construction of hydrologic virtual network,can not only solve the hydrological station network in real time flood forecast,but also realize the internal resource sharing,and internal office automation system access of the dispersed sites in the absence of special internal network.After nearly a year of the production run,Shandong hydrology,water level station reporting effectiveness greatly increased,the error rate was almost zero,gained apparent benefit.
