摘　　要：介绍了5G承载的需求和网络演进原则,分析比较了5G承载网络的三种演进方案,即分组增强型OTN方案,基于IP RAN的升级方案,切片分组网,最后介绍了5G承载基于SDN的远期演进目标。The requirements of 5G carrying and the principle of network evolution are described. Three evolution schemes on 5G carrying network are analyzed and compared, including packet enhanced OTN scheme, upgraded IP RAN scheme and slicing packet network. Finally, the long-term evolution goal based on SDN for 5G is discussed.
