Due to the support of enormous network protocols,IP network device results in high complexity.Not only does it limit the IP network technology development,will not be able to meet the current application trend of cloud computing,big data and server virtualization.Software defined networking(SDN) as a latest network norm making network device programmable with the Abstraction redefinition of control plane is expected to solve above issues.This paper introduced the background,characteristics and development status of OpenFlow,it analyzed OpenFlow-based SDN architecture and key technologies.Furthermore,it discussed different SDN research directions,such as the automation of network management,the unified control of optical transmission and IP bearing,smooth switching in wireless network,network virtualization and QoS assurance.
