NAT在配置医院连接医保数据中心中的应用

Application of NAT Connection Between Configuration Hospital and Medicare Data Center

目的:为了满足医保病人的需求,利用医院现有的网络设备,在不改变目前网络结构的情况下实现同医保局数据中心相连。方法:使用网络地址转换功能(NAT),把医院需要同医保数据中心相连的设备地址转换成医保数据中心给出的合法地址。结果:利用现有设备NAT功能,减少了网络设备的重购,成功实现同医保数据中心相连。结论:使用NAT没有改变本地设备的IP地址,有效地克服了合法IP地址的不足,并且使网络安全得到更进一步的加强。

Objective In order to meet the needs of Medicare patients, hospitals use existing network equipment to implement the connection with Data Center of Medicare without changing the present frame. Methods Network Address Translation function （NAT） was used to translate equipment IP address that hospital needs to connect with data center of Medicare into legal IP address in data center of medicare. Results The author used existing NAT function of equipment to reduce the repeating purchase for network equipment and successfully realized the connection between hospital and Data Center of Medicare. Conclusion Using NAT devices not only does not need to change the local IP address but effectively overcomes the lack of legal IP addresses, and what＇s more, network security is further strengthened.
