CDMA VPDN构建IP数字测震台网
|
摘要
通过对目前CDMA 2000 1x网络技术和构架的深入介绍,可了解CDMA VPDN的应用原理。针对CDMA传输的早期台网方案在应用中的不足,以四川省数字测震台网为例,详细介绍了利用CDMA VPDN构建IP数字测震台网的组网方式和网络构架。最后,对该方案使用中存在的一些常见问题给予了详细分析并针对问题提出了处理方法和建议。
As an advanced CDMA network technology,CDMA VPDN has solved many problems occurred in early CDMA network applications.In order to achieve a good understanding of its application mechanism,this article began with an introduction of CDMA 2001 1x network techniques and structures.Then taking Sichuan digital seismic observation networks as an example,we particularly illustrated the structure form and fashion of CDMA VPDN IP digital seismic observation networks.Lastly,common problems and their solutions in CDMA VPDN IP networks were discussed.
