摘　　要：软件定义网络SDN(Software Defined Network)是数据与控制平面分离,并且网络可以编程的一种新型网络架构。随着全光网络以及超100G的发展,光网络如何适应云计算以及数据中心等新型应用是光网络未来发展的一个重要议题。SDN的提出为光网络发展带来了启发。文章阐述了SDON的架构,发展背景以及现状,分析了体系架构下各个层面和接口的关键技术,研究了要实现软件定义光网络各个层面所需进一步解决的技术难题,归纳提出了系统整体研究思路和实现方法途径。SDN is a new network archirecture whose data and control plane is separated and whose network can be programmed. With the development of all optical network and 100 G opti- cal network, adapting to the cloud computing and data center application model is an important development of optical network in the future. SDN has brought inspiration to the development of optical networks. The Software Defined Optical Network （SDON） architecture development and current situation were introduced. The key technologies of the architecture were analyzed. Finally, the technical problems that need to be solved in the realization of software defined optical net- work were researched. The methods for SDON research and realization were summarized.
