摘要:

软件定义网络已经在不同类型的网络中实现了巨大的增长和部署。与传统网络相比,它将控制逻辑从网络层设备中分离出来,并将其集中起来,以实现跨域的高效流量转发和流量管理。这种多层架构在数据平面的底部具有数据转发设备,这些设备由控制平面中的控制器编程。高级应用或管理平面与控制层交互,以编程整个网络并执行不同的策略。这些层之间的交互是通过作为通信/编程协议的接口完成的。在这次调查中,我们提出了一个全面的研究,这样的接口可用于南行,北行,东/西行通信。我们根据它们的特性和能力将每种类型分为不同的类别。网络设备的虚拟化是软件定义网络中的常见做法。本文还分析了不同虚拟化方案下的接口解决方案。此外,本文强调了一些短期和长期的研究挑战和开放的SDN接口相关的问题。

英文摘要:

Software Defined Networks has seen tremendous growth and deployment in different types of networks. Compared to traditional networks it decouples the control logic from network layer devices, and centralizes it for efficient traffic forwarding and flow management across the domain. This multi-layered architecture has data forwarding devices at the bottom in data plane, which are programmed by controllers in the control plane. The high level application or management plane interacts with control layer to program the whole network and enforce different policies. The interaction among these layers is done through interfaces which work as communication/programming protocols. In this survey, we present a comprehensive study of such interfaces available for southbound, northbound, and east/westbound communication. We have classified each type into different categories based on their properties and capabilities. Virtualization of networks devices is a common practice in Software Defined Networks. This paper also analyzes interface solution which work with different virtualization schemes. In addition, the paper highlights a number of short term and long term research challenges and open issues related to SDN interfaces.
