Survey of intent-based networking

Abstract： In order to meet rapidly changing business and user needs, intent-based networking(IBN) is proposed by the industry. In the IBN，natural language is directly used to describe "service intent" and automatically translated into strategies and operations that can be performed by the network, thereby reducing the complexity of network management, greatly improving operation and maintenance and also largely achieving labor-saving. In this article, IBN-related projects and research is extensively and deeply investigated, the concept of intent, the intent-based northbound interface(NBI), the relationship between intent and policy as well as representative IBN frameworks are introduced, and also the main challenges of IBN deployment and application are discussed. The goal of this article is to provide readers with a comprehensive view of IBN.
