从NetIDE项目中吸取的经验教训：将SDN编程提升到新的水平
Lessons learnt from the NetIDE project: Taking SDN programming to the next level
摘要：
SDN承诺通过在运营商网络中实现多供应商硬件和软件生态系统来克服供应商锁定。然而，我们注意到，目前没有发生这种情况。一个允许组合不同框架的SDN应用程序的框架可以帮助扭转这一趋势。在本文中，我们分析了当前SDN景观中的挑战，然后介绍了NetIDE项目开发的多控制器SDN框架。我们的架构支持不同的SDN南向协议，我们已经使用OpenFlow协议实现了概念验证，这使我们对其缺点有了更深入的了解。
英文摘要：
SDN promises to overcome vendor lock-in by enabling a multi-vendor hardware and software ecosystem in operator networks. However, we observe that this is currently not happening. A framework allowing to compose SDN applications combining different frameworks can help revert the trend. In this paper, we analyze the challenges in the current SDN landscape and then present the multi-controller SDN framework developed by the NetIDE project. Our architecture supports different SDN southbound protocols and we have implemented a proof of concept using the OpenFlow protocol, which has given us a greater insight on its shortcomings.
