Abstract: 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 multimodal 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.
Keywords: tactile Internet; network architecture; multimodal communication; semantic communication; communication-computing-caching fusion scheduling
