Abstract

Abstract:

Information and communication technology is currently experiencing a phase of accelerated integration, systematic innovation and intelligent driving evolution. Based on digital twin technology, the construction of a self-intelligent optical network with self-configuration, self-optimization, and self-repair capabilities has become a research hotspot. This technology aims to achieve intelligence and automation throughout the full life cycle of optical network planning, construction, maintenance, optimization, and operation. This paper comprehensively analyzes the current research status of digital twin technology at home and abroad. It proposes a novel self-intelligent optical communication network architecture, and designs a quantitative representation model for optical network data using high-dimensional space. Additionally, it constructs a complete simulation modeling operations set for digital twin. Aiming at the current optical network operation and maintenance challenges, this paper sorts out three types of digital twin application scenarios. Using the cases of network transmission quality evaluation and autonomous optimization, this paper describes the application effect of digital twin technology, and summarizes and prospects the digital twin technology.

Key words: optical transport network, intelligent optical network, digital twin, simulation modelling
