软件定义网络（SDN）和灵活的网格光传输技术是两项关键技术，允许网络运营商根据应用需求定制其基础设施，从而最大限度地减少托管新应用所需的额外资本和运营成本。在本文中，我们首次报告了一种基于 OpenFlow 的新型 SDN 统一控制平面的设计、实现和演示，该控制平面允许跨异构最先进的光和数据包传输域进行无缝操作。我们验证并实验评估了灵活的 DWDM 网格传输技术的 OpenFlow 协议扩展及其与固定 DWDM 网格和第 2 层数据包交换的集成。
Software defined networking (SDN) and flexible grid optical transport technology are two key technologies that allow network operators to customize their infrastructure based on application requirements and therefore minimizing the extra capital and operational costs required for hosting new applications. In this paper, for the first time we report on design, implementation & demonstration of a novel OpenFlow based SDN unified control plane allowing seamless operation across heterogeneous state-of-the-art optical and packet transport domains. We verify and experimentally evaluate OpenFlow protocol extensions for flexible DWDM grid transport technology along with its integration with fixed DWDM grid and layer-2 packet switching.
