[Abstract] Soft defined network (SDN) is one of the core technologies in the NovoNet project of China Mobile. The major scenarios of SDN practice of China Mobile are including data center, defined packet transport network (SPTN), wide area network (WAN), NovoVPN and mobile core network. It is considered that combing the software with network, SDN brings flexibility and openness to the network, while has an impact on the inherent stability of the network. For SDN using, a overall consideration of the demand and balance in business systems for stability and flexibility should be taken into.
