软件定义光传送网采用集中式的控制器进行网络控制，控制器的性能及其测试方法是判断其是否存在性能“瓶颈”的重要手段。文章对评测控制器性能“瓶颈”的性能指标进行了分析，在此基础上，提出了一种针对控制器长期运行性能指标的测试方法，采用此方法可对控制器长期运行的稳定性、可靠性及性能进行综合评判。

The software defined optical transport networks uses a centralized controller. The performance of the controller and the corresponding test methods become an important method to find the “bottleneck” of networks. The performance of the controller is evaluated and analyzed in this paper considering the “bottleneck”. Then, a test method used to evaluate the long-term performance of controller is presented, which can be used to evaluate the stability and reliability of the controller in a comprehensive way.
