Survey on digital twin network towards 6G:Architectures,applications and challenges
The digital twin network(DTN)is an emerging network that uses digital twin(DT)technology to create virtual replicas of physical objects.With DT technology,DTN will enhance the capabilities of 6G networks in many ways,inclu-ding intelligent fault management,intelligent network optimization and management,and endogenous network intelligence,helping to achieve a highly simplified,intelligent,and automated network.This paper comprehensively studies DTN,first outlining its key features and definitions.Secondly,this paper describes the architecture,protocols,interfaces and lifecycle management of DTN.Then,the applications of DTN in model management and deployment,resource management and scheduling,security and privacy protection,intelligent network operation and maintenance,and intelligent transportation are elaborated.Finally,the challenges and prospects of DTN are pointed out.
