摘　　要：在新型业务需求和新技术涌现的双重驱动下,软件定义网络(SDN)成为互联网应用提供商、运营商、IT系统和网络设备提供商共同关注的新型网络架构和技术。这种网络控制与转发能力分离的架构,可以支持更灵活的网络控制和业务能力提供。从SDN的概念和总体架构出发,分析IP RAN对SDN的需求,提出了在IP RAN中引入SDN技术的目标网络结构和网络模型,并对基于SDN的IP RAN应用策略进行了探讨。The With the development of new applications and technologies, software defined networking is getting more attention from application providers, carriers, and IT system and network devices vendors. In SDN, the control and data planes are decoupled, which supports programmable network control and service provision. The definition and framework of SDN were discussed; the demands of IP RAN in SDN in current telecommunication network were analyzed. The target network structure and network models based SDN in IP RAN network were described and the application strategy of SDN in IP RAN network was also discussed.
