摘 要:SDN 软件定义网络作为目前网络行业中最炙手可热的新技术正在蓬勃发展,越来越多传统网络设备厂商和互联网公司也在持续跟进并不断丰富和完善各自的SDN 网络解决方案。在主流的SDN 网络解决方案中,根据可编程接口方向层级可分为南向接口和北向接口,南向接口通常作为SDN 控制器对网络设备进行控制的接口协议;北向接口通常用于SDN 控制器对接业务应用系统和第三方系统的协议。本文简要阐述业内主流的SDN 对外的南北向接口协议及适应的场景。

Abstract:SDN software definition network as the hottest new technology in the network industry is developing vigorously. More and more traditional network equipment manufacturers and internet companies are continually following up and constantly enriching and improving their SDN network solutions. In the mainstream SDN network solution,according to the direction hierarchy of programmable interface,it can be divided into south-facing interface and north-facing interface. The south-facing interface is usually used as the interface protocol of SDN controller to control network equipment. The north-facing interface is usually used for the protocol of SDN controller docking business application system and third-party system. This paper briefly describes the industry’s mainstream SNN external northsouth interface protocol and adaptation scenarios.
Keywords:SDN;network equipment;controller;north-facing interface;south-facing interface
