摘要
为了顺应6G网络发展趋势,围绕触觉互联网(TI)超低时延、超高可靠的关键性能需求,从网络架构、信息传输、资源管理3个层面系统性地提出了TI关键使能技术框架。在网络架构方面,提出基于软件定义网络(SDN)/网络功能虚拟化(NFV)和人工智能(AI)赋能的新型网络架构;在信息传输方面,提出采用多模态通信增强沉浸体验,并利用语义通信促进智能体间的达意通信;在资源管理方面,提出通过通信-计算-存储多维资源融合调度来提高网络服务承载能力。最后,探讨了TI在发展和应用中存在的问题、挑战以及可能的解决思路。
Following the development trend of 6G networks and focusing on the key performance requirements of the tactile Internet(TI)for ultra-low latency and ultra-high reliability,TI’s key enabling technology framework is systematically proposed from three levels including network architecture,information transmission,and resource management.In terms of network architecture,a new network architecture based on software defined-network(SDN)/network function virtualization(NFV)and artificial intelligence(AI)is proposed.In terms of information transmission,it is proposed to use multi-modal communication to enhance the immersive experience,and to use semantic communication to promote idea-passing communication between agents.In terms of resource management,it is proposed to improve the carrying capacity of network services through the integration of communication-computing-caching multi-dimensional resource scheduling.Finally,the problems,challenges,and possible solutions in TI’s development and application are discussed.
