1. Introduction
With the advent of 5G, Internet of Things and Cloud Computing, the
scale of network is expanding constantly. Accordingly, the network
operation and maintenance are becoming more complex due to higher
complexity of network; and innovations on network will be more and
more difficult due to the higher risk of network failure and higher
trial cost.
Digital twin is the real-time representation of physical entities in
the digital world. It has the characteristics of virtual-reality
integration and real-time interaction, iterative operation and
optimization, as well as full life-cycle, and full business data-
