[Abstract] Due to the advantages of centralized control, forwarding and control separation, and open network capability, soft defined network (SDN) will be the main supporting technology of future network to deal with major challenges, such as Internet of everything, complex and various business, continuously increasing bandwidth, etc. ZTE focus on the practice and innovation of SDN technology which is combined with cloud computing and open network technology. Major related application scenarios such as data center network, wide area network (WAN), 5G network slices, on-demand network (fusion of cloud and network) are discussed. Meanwhile, we propose the key technology development direction in the future.
