摘 要：针对现有的物联网统一管理和编排难实现、数据传输时延高可靠性低这两个问题，提出了基于意图驱动物联网架构的解决方案。新型的物联网参考架构融合了现有物联网架构、软件定义网络架构和网络功能虚拟化架构的优势，不仅可以解决网络统一管理难的问题，而且可以实现意图的生成、意图转译为策略、策略下发执行的过程。为了满足用户对于网络服务方面的不同需求，即低时延高可靠性传输，提出了实现基于意图的自适应路由选择，并通过仿真验证证明该方法可行。

Abstract：Aiming at the two problems of the unified management and orchestration of the existing IoT，the high data transmission delay and low reliability，a solution based on the intention-driven IoT architecture is proposed. The new IoT reference architecture combines the advantages of the existing IoT architecture，software-defined network architecture and network function virtualization architecture. It can not only solve the difficult problem of unified network management，but also realize the generation of intentions and the translation of intentions into strategies and tactics deliver the execution process. In order to meet the different needs of users for network services，that is，low-latency and high-reliability transmission，it is proposed to implement intent-based adaptive routing according to the needs，and simulation proves that the method is feasible.
