To meet the needs of digital transformation of the industry, basic telecommunications enterprises speed up the upgrading of backbone networks, metropolitan area networks and 5G networks, and enhance the service capabilities of enterprise private lines, home broadband and mobile terminals based on segmented routing, network slicing, flow detection, application-aware networks, service function chain (SFC) and other technologies. We will promote the construction of a new data center. Support data center, cloud service and content distribution network enterprises to upgrade network infrastructure based on "IPv6+" technologies such as segmented routing, intelligent lossless, automatic control and application-aware network, and promote new Internet data centers and industry data centers to have IPv6 single-stack deployment capability. Through the evolution and upgrading of IPv6 technology, we can promote the coordinated development of data center, cloud computing and network, and constantly improve the network transmission quality and service experience between data centers.
