摘　　要：为了适应宽带业务与应用的持续发展,光网络需要变得更加灵活可控。软件定义光网络(SDON)聚焦于将软件定义技术融入光网络的综合解决方案,其关键技术涉及软件定义光传输、交换和联网等。通过分析SDON的技术特征,探讨了SDON引入光网络的必要性和可行性,设计了SDON的典型应用案例,并可以预见SDON在支撑新一代光网络向智能高效、灵活调度、虚拟重构等方向的发展进程中将发挥重要作用。In order to meet the requirement of continued growth in broadband services and applications, optical networks need to be more and more flexible and controllable. Software defined optical network（SDON） focuses on an integrated optical networking solution based on software defined technology, and the key technologies are related to software-defined optical transmission, switching and networking, etc. Based on the analysis of technological characteristics of SDON, the necessity and feasibility of introducing SDON were discussed, and several application scenarios of SDON were proposed. All these show that SDON will play an important role in the development process of next-generation intelligent optical networks forwards to high efficiency, flexible scheduling, and virtual reconstruction.
