[摘要] 网络模型及北向接口（NBI）是软件定义网络（SDN）中的关键问题。根据业界标准发展情况，提出了网络模型分为网络业务模型、网管模型、功能模型和网络设备模型，并指出了不同的模型对应了不同的需求。认为运营商、大型厂商等应定义统一的SDN模型和接口，能够推动产业链的成熟和统一。

[Abstract] Network model and northbound interface (NBI) are the key issues in soft defined network (SDN). In this paper, network model is divided into service model, management model, function model and device model. And different needs corresponding to different models are also pointed out. Operators, large manufacturers and so on should define a unified SDN model and interface, so as to promote the maturity and unity of the industrial chain.
