摘　　要：SDN将网络的控制平面从交换机和路由器中的数据平面分离出来,代表着虚拟化从服务器到网络的演变。SDN如今已深入到网络架构的各个方面,其最大优势在于可以动态地为不同的互联网业务分配带宽资源。本文从SDN的定义及内涵入手,归纳SDN的关键技术和标准化研究进程,并结合网络设备商和运营商的SDN部署情况对产业现状进行深入的分析和总结。The concept of SDN is to isolate the control plane from the data plane, which represents the virtualization evolution developing from the server to the network. SDN now has already gone deep into all aspects of network architecture. The biggest advantage is that it can allocate bandwidth resources for any different Internet services dynamically. This paper begins from the definition, and then sums up the SDN key technologies and its standardization research process, finally analysis and summary the development of the network industry from both vendors＇ and operations＇ sides.
