摘要
软件定义网络(SDN)作为一种新的网络架构,为打破传统的TCP/IP架构提供了可能,实现了控制平面与数据平面的解耦,可以满足未来互联网的需求。基于OpenFlow的SDN可以为新的网络应用与未来互联网技术的发展提供支持。基于此,从专利角度系统梳理基于OpenFlow的SDN技术的专利申请,对国内外专利申请量趋势、重要申请人分布及研究和发展重点进行可视化展示。
As a new network architecture,Software Definition Network(SDN)provides the possibility to break the traditional TCP/IP architecture,realizes the decoupling of control plane and data plane,and can meet the needs of the future Internet.OpenFlowbased SDN can provide support for new network applications and future Internet technology development.Based on this,the patent applications of SDN technology based on OpenFlow are systematically sorted out from the patent point of view,and the trend of patent applications at home and abroad,the distribution of important applicants and the focus of research and development are visualized.
