软件定义网络(SDN)一词在当今有关未来通信网络的讨论中非常流行。然而，与任何新的术语或范例一样，关于这项技术还没有形成一致的定义。对SDN的零散看法导致设备供应商将遗留产品冒充为SDN，学者将SDN的属性与网络虚拟化的属性混淆，用户没有充分了解其好处。因此，将SDN建立为一项超越实验室和孤岛部署的广泛采用的技术，需要一个指南针来导航当今构成SDN的众多想法和概念。本文的贡献代表着朝着这样一个工具迈出的重要一步。它给出了SDN及其接口的完整定义，并列出了其关键属性。此外，还提供了接口和属性到SDN用例的映射，突出了接口和属性与每个场景的相关性。这个指南针为SDN的潜在采用者提供指导，告诉他们SDN是否确实是特定用例的正确技术。
The term Software Defined Networking (SDN) is prevalent in today's discussion about future communication networks. As with any new term or paradigm, however, no consistent definition regarding this technology has formed. The fragmented view on SDN results in legacy products being passed off by equipment vendors as SDN, academics mixing up the attributes of SDN with those of network virtualization, and users not fully understanding the benefits. Therefore, establishing SDN as a widely adopted technology beyond laboratories and insular deployments requires a compass to navigate the multitude of ideas and concepts that make up SDN today.The contribution of this article represents an important step toward such an instrument. It gives a thorough definition of SDN and its interfaces as well as a list of its key attributes. Furthermore, a mapping of interfaces and attributes to SDN use cases is provided, highlighting the relevance of the interfaces and attributes for each scenario. This compass gives guidance to a potential adopter of SDN on whether SDN is in fact the right technology for a specific use case.
