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.
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.
