Abstract:

5G and cloud era has come,SRv6 and EVPN are the key technologies in the evolution of cloud network integration.The development process of network protocol was reviewed,the birth background,technical principles and advantages of SRv6 and EVPN were analyzed,and the application scenarios and deployment strategies of SRv6+EVPN were studied combined with the STN architecture of China Telecom 5G bearer network,China Telecom 5G development strategy and 2B service.Finally,the actual situation of China Telecom’s STN deployment of SRv6+EVPN was introduced,and the overall deployment of SRv6+EVPN technology in metropolitan + backbone cloud network integration infrastructure was forecasted.

Key words: STN, SRv6, EVPN, MPLS, VPLS
