摘要
首先阐述了PTN+CE承载LTE的组网方式以及该方式存在的不足,再对PTN支持L3 VPN工作方式和具体实现过程进行了介绍,最后通过现网测试结果描述PTN开启L3 VPN功能后回传网中的保护倒换性能,说明了该方案实现LTE回传承载的可行性。
This article first represents the LTE bearing networking mode of PTN＋CE and the disadvantages of this mode. Then, the working mode and the realization process of PTN supporting L3 VPN technology are introduced. Finally, through the present network test results, the protection switching quality of backhaul network based on PTN supporting L3 VPN technology is described, which indicates the feasibility of realizing LTE backhaul by this mode.
