摘要
软件定义网络使网络具备可编程的能力,与网络应用程序关联的SDN控制器北向接口成为提高网络性能关键。基于Intent的SDN北向接口研究在近几年被重视,成为北向接口的发展趋势,文章介绍了Intent NBI(Northbound Interface)的基本概念以及标准化工作,详细描述了两大开源组织Open Stack与Open Day Light中的Intent NBI研究进展,并重点介绍了其中具有代表性的一些项目。
The programmability of network is enabled in SDN（Software-defined network）, therefore, the Northbound Interface（NBI） of SDN which associated with network applications becomes the key factor to the network performance improvement. Recent researches focus on the Intent based NBI, and the Intent based NBI becomes the trend of the NBI development. The conception and the standardization work of the intent NBI are introduced in this paper, and the current researches and projects in Open Stack and Open Daylight on Intent NBI are described in detail.
