在光流交换网络中，控制平面管理数据平面、执行调度、重新配置网络等。对于大型广域网，数据平面的规模和请求的随机性对实现数据平面的响应性/效率和控制平面的可扩展性构成了巨大挑战。在这项工作中，我们给出了一个概述的控制功能和调度算法的OFS网络。我们考虑两种可能的WAN光路拓扑结构：网状或隧道。我们使用阻塞概率和数据平面的吞吐量提供了一个共同的平台，控制平面的设计和算法复杂度的性能比较。由于流量需求很高，隧道架构提供了与网状架构相当的数据平面性能，但需要的网络管理和控制流量以及处理复杂性要少得多，因此更适合大型网络。
In Optical Flow Switched networks, the control plane manages the data plane, performs scheduling, reconfigures the network, etc. For large wide area networks the scale of the data plane and the stochastic nature of the requests pose big challenges in achieving both data plane responsiveness/efficiency and control plane scalability which are coupled. In this work, we give an overview of the control functions and a scheduling algorithm for an OFS network. We consider two possible WAN lightpath topology architectures: meshed or tunneled. We use the blocking probability and throughput of the data plane to provide a common platform for the performance comparison of the designs of the control plane and algorithm complexity. With high traffic demands, the tunneled architecture provides comparable data plane performance as the meshed architecture but requires much less network management and control traffic and processing complexity and is thus much more scalable to large networks.
