摘要
组建EPC Pool后,当EPC发生故障时S1-Flex需进行切换,通过分析EPC与PTN落地设备的对接配置方案、LTE业务的转发路径、PTN系统的L2/L3与纯L3路由发布和L3 VPN的业务模型,探讨城域网L2/L3与纯L3设备和省干落地设备与纯L3设备间的L3 VPN路由配置方案,实现PTN系统与EPC Pool的协同配合,进而提高PTN和LTE业务安全性。
After the formation of the EPC pool,the S1-Flex need to switch when the EPC is failure. By analyzing the docking configuration scheme of EPC and PTN landing equipment,the forwarding path of LTE service,the routing issue between L2/L3 and pure L3 of PTN system,VPN L3 business model,it discusses the VPN L3 routing scheme between the MAN L2/L3 and pure L3 equipment,it discusses the L3 VPN routing scheme between provincial ground equipment and pure L3 equipment. The synergy of PTN system and EPC pool is realized,the safety of PTN network and LTE service is improved.
