[Abstract] The new slicing packet network infrastructure and key technologies for 5G backhaul network are introduced in this paper. Integrating the segment routing, Ethernet virtual private network (EVPN) technology and L3 to edge deployment scheme, the minimized IP network technology is proposed. Meanwhile, the application of slicing technology, new optical module technology and network automation in 5G backhaul network are studied. Then a new automatic 5G backhaul network architecture which organically integrates these new technologies is put forward. And this architecture provides an important basis for 5G backhaul technology development and network construction.
