| 摘要: |
| 随着互联网规模的不断增大，网络管理和运维变得极其复杂，网络自治成为未来网络发展的趋势，基于意图的网络（intent-based networking，简称IBN）应运而生.首先从IBN的定义入手，介绍学术界及产业界对IBN范畴及体系结构的描述，并概述IBN实现的闭环，包括意图获取、意图转译、策略验证、意图下发与执行、实时反馈及优化；其次，按照IBN闭环，详细阐述IBN关键技术的研究现状；随后，举例说明IBN在网络测量和网络业务编排中的应用；最后，展望未来研究工作并总结全文. |

| Abstract: |
| With the increasing scale of the Internet, network management and operations become extremely complex. Intent-based networking (IBN) emerges when network autonomy becomes a major trend of future network. First of all, this paper gives the definition of IBN, and describes the IBN category and architecture in academia and industry. The implementation closed-loop of IBN is also summarized, including intent acquisition, intent translation, policy verification, intent distribution and execution, real-time feedback and optimization. Then, key technologies of IBN implementation are elaborated in detail according to the IBN closed-loop. In addition, examples are given to illustrate the IBN-based applications from the aspects of network measurement and network service orchestration. Finally, the future research work is prospected and the whole paper is concluded. |
