[Abstract] Software defined network (SDN) is now widely concerned and valued. It can significantly improve controllability and flexibility of the existing network, and effectively reduce the capital expenditures(CAPEX) and operating expense(OPEX) for network service providers. SDN evolution, is moving towards to a more open, more intelligent, more large-scale direction, and will better support the development of future network. Moreover, with rapid development of SDN, the demand for corresponding talents will become one of the important problems to be solved.
